066e8a4557 CMake: Handle missing packages in project compile tests
If a find_package() in a try_compile project doesn't find a package,
and we then link against a non-existent target, the configuration
failure of the compile test also fails the configuration of the
project.

To avoid that, separate library targets from non-targets, and make sure
to only link against the targets if they exist.

pro2cmake now outputs modified compile test project code which iterates
over targets and non-target libraries, and links against them when
needed.

e0346df1b2 CMake: Handle finding of OpenSSL headers correctly
In Coin when provisioning for Android, we download and configure
the OpenSSL package, but don't actually build it. This means that
find_package(OpenSSL) can find the headers, but not the library,
and thus the package is marked as not found.

Previously the openssl_headers feature used the result of finding
the OpenSSL package, which led to it being disabled in the above
described Android case.

Introduce 2 new find scripts FindWrapOpenSSL and
FindWrapOpenSSLHeaders. FindWrapOpenSSLHeaders wraps FindOpenSSL,
and checks if the headers were found, regardless of the OpenSSL_FOUND
value, which can be used for implementing the openssl_headers feature.

FindWrapOpenSSL uses FindWrapOpenSSLHeaders, and simply wraps the
OpenSSL target if available.

The find scripts also have to set CMAKE_FIND_ROOT_PATH for Android.
Otherwise when someone passes in an OPENSSL_ROOT_DIR, its value will
always be prepended to the Android sysroot, causing the package not
to be found.

Adjust the mapping in helper.py to use the targets created by these
find scripts. This also replaces the openssl/nolink target.

Adjust the projects and tests to use the new target names.

Adjust the compile tests for dtls and oscp to use the
WrapOpenSSLHeaders target, so that the features can be enabled even
if the library is dlopen-ed (like on Android).

0bfbe10ff2 CMake: Implement proper exclusion of tools including installing
The previous approach didn't work for prefix builds. While a target
might be excluded from building via EXCLUDE_FROM_ALL property, when
calling make install it would still try to install the target and
thus fail.

It's not possible to modify an install() command in a post-processing
step, so we switch the semantics around.

pro2cmake will now write a
qt_exclude_tool_directories_from_default_target() call before adding
subdirectories. This will set an internal variable with a list
of the given subdirectories, which is checked by qt_add_executable.

If the current source dir matches one of the given subdirectories,
the EXCLUDE_FROM_ALL property is set both for the target and the
qt_install() command.

This should fix the failing Android prefix builds of qttools.

d2931a2626 CMake: Handle standalone config.tests in configure libraries section
Some library entries in configure.json have a test entry.
An example is assimp in qtquick3d.

qmake tries to find the library via the sources section, and then tries
to compile the test found in config.tests/assimp/assimp.pro while
automagically passing it the include and link flags it found for assimp.

We didn't handle that in CMake, and now we kind of do.

configurejson2cmake will now create a corresponding
qt_config_compile_test call where it will pass a list of packages and
libraries to find and link against.

pro2cmake will in turn generate new code for the standalone
config.test project. This code will iterate over packages that need to
be found (like WrapAssimp) and then link against a list of passed-in
targets.

In this way the config.test/assimp/main.cpp file can successfully
use assimp code (due to propagated include headers).

qt_config_compile_test is augmented to take a new PACKAGES argument,
with an example as follows

PACKAGES PACKAGE Foo 6 COMPONENTS Bar
         PACKAGE Baz REQUIRED

The arguments will be parsed and passed to the try_compile project,
to call find_package() on them.

We also need to pass the C/C++ standard values to the try_compile
project, as well as other try_compile specific flags, like the
toolchain, as given by qt_get_platform_try_compile_vars().

which has a slash (platforms/darwin).

622894f96e CMake: Allow excluding tools and apps from the default 'all' target
Qt uses the qtNomakeTools() function to mark a directory which will
not be built as part of the default target. This is especially
important when cross-compiling (to iOS for example) because the build
process might fail.

The condition for not building these "GUI tool sub-directory projects"
is the absence of the "tools" value in qmake's QT_BUILD_PARTS
variable.

Introduce a QT_NO_MAKE_TOOLS CMake variable. If the value is true,
it's equivalent to "tools" not being present in QT_BUILD_PARTS.

Introduce qt_exclude_tool_directories_from_default_target().
It's the qmake counter part to qtNomakeTools().

Teach pro2cmake to generate it where appropriate.

7c04c5427f CMake: Fix creation of forwarding headers to be at configure time
qt_add_module checks for the existence of the following directory
include/QtFoo/6.0.0/Foo when deciding whether a private module target
should contain that path in its INTERFACE_INCLUDE_DIRECTORIES.

There are 2 cases when it's created, when running syncqt, and inside
qt_install_injections. If syncqt doesn't create it because there are no
private headers (like in qttools/src/global), qt_install_injections
created it at generation time (for injected configure headers like
qttools-config_p.h)

Unfortunately that caused the existence check mentioned above to fail,
not exporting the path in the QtToolsPrivate's include directories,
and failing the qttools build.

To fix that, create the injection files (and directories) at configure
time, using qt_configure_file instead of file(GENERATE).

e510a4e327 CMake: Introduce qt_configure_file
It has the same kind of signature as file(GENERATE) but
creates the files at configure time rather than generation time.

CMake provides a few ways to generate files
file(WRITE) -> always overrides content
configure_file() -> only overrides if content changes, creates file
                    at configure time, can only take a file as input
file(GENERATE)   -> only overrides if content changes, creats file
                    at generation time, can take a string or file
                    as input

Because dealing with an input file is a hassle (need to create one,
make sure it's installed, make sure it's used correctly in the
various build types like super-build, non-prefix-build, etc)
people tend to use file(GENERATE) instead, which can take a string
argument, and is thus easier to use.

Unfortunately that introduces subtle bugs because the
file is created at generation time, but there are existence
checks which are done at configuration time.

Thus qt_configure_file allows creation of files at configure time,
without having to provide an input file. Underneath it uses
configure_file(). Once CMake 3.18 is released, the implementation
can be switched to use file(CONFIGURE).

1f442c684f CMake: Provide script to configure and build one or more tests
Before this patch there were a few ways to build tests
- Configure all tests as part of the repo build
- Configure all tests as part of the repo build, but don't build
  tests by default (-DQT_NO_MAKE_TESTS=ON)
- Configure all tests as a standalone project in a separate build
  dir using -QT_BUILD_STANDALONE_TESTS=ON

All of the above incur some time overhead due to the necessity
of configuring all tests.
Sometimes you just want to build ONE test (or a few).

To facilitate that use case, a new shell script called
bin/qt-cmake-standalone-test(.bat) can now be used to configure
and build one or more tests.

The script takes one single argument pointing to the desired test
project path and configures a generic template project that sets up
all the necessary Qt CMake private API, afterwards calling
add_subdirectory on the passed in project.

Example
$ path/to/qt/bin/qt-cmake-standalone-test ./tests/auto/gui/image/qicon

or

$ path/to/qt/bin/qt-cmake-standalone-test ./tests/auto/gui/image

After that, simply run 'ninja && ctest' to build and run the test(s).

This is the CMake equivalent of calling qmake on a test .pro file
(or on a tests SUBDIRS .pro file)

There are 3 details worth mentioning.

Due to the add_subdirectory call, the built artifacts will not
be in the top-level build dir, but rather in a nested build_dir.

The script currently can't handle more than one argument
(the path to the project), so you can't pass additional
-DFoo=bar arguments.

If a test uses a 3rd party library (like Threads::Threads)
which was not a public dependency for any of the Qt modules,
configuration will fail saying that the target was not found.
Perhaps we should consider recording these packages when
generating the StandaloneConfig.cmake files.

For example 'ninja html_docs_qtbase' or 'ninja html_docs_Core'.

Now there's a global / top-level target called

For super builds it will build the documentation of all
configured repositories.

For a single repo build, it's equivalent to calling
'ninja docs_repo_name'.

Also for consistency, add the "docs_Core" target, which was missing
before. So now a 'docs' target exsits for repo names AND targets.

New global target names are
- docs
- prepare_docs
- generate_docs
- html_docs
- qch_docs
- install_html_docs_docs
- install_qch_docs_docs

architecture in question. The latter can cause the build to fail in
conjunction with warnings as errors.

We make sure the file is only picked up on macOS, not iOS and friends,
since those platforms require another principal class. If needed we can
extract the value out as a CMake variable and use the same file for all
Apple platforms. Doing so would assume all keys are single-platform
only, so if that's not the case we need platform-specific files.

We should probably extract the package type out as a variable too,
so that the file can be used for both apps, plugins, and frameworks,
but doing so requires setting up that variable somewhere based on
the target type, which CMake doesn't allow in an easy way.

The file itself is based on the file CMake ships, combined with
keys inherited from Qt's existing plist templates for qmake, and
adjusted to match what Xcode generates by default these days.

b04d087bd0 CMake: Handle path components like INSTALL_LIBDIR more correctly
We recomputed INSTALL_LIBDIR for every new repo that is configured,
which is incorrect due losing any custom provided libdir when
configuring qtbase.

Save that information (and all other path components) in
QtBuildInternalsConfigExtra.cmake.
Make sure not to-recompute that information when configuring a project
other than QtBase.

Allow providing absolute paths instead of relative paths for these
variables.

Note that only absolute paths pointing somewhere under
the prefix will currently work, otherwise configuraion will fail. If
we need to support such a use case, we'll have to carefully check all
code that use these path components to make sure they handle absolute
paths correctly (current assumption is relative paths everywhere).

Use the computed paths when generating the qconfig.cpp file which is
used for qmake -query.

95e1469eb8 CMake: Port most of the configure summary support
Teaches configurejson2cmake about summaries / reports, so things
like enabled features, configure sections, notes, etc.

Add relevant CMake API for adding summary sections and entries,
as well as configure reports. The commands record the passed data,
and the data is later evaluated when the summary needs to be printed.
This is needed, to ensure that all features are evaluated by the
time the summary is printed.

Some report and summary entries are not generated if they mention a
feature that is explicitly exclduded by configurejson2cmake's feature
mapping dictionary. This is to prevent CMake from failing at configure
time when trying to evaluate an unknown feature. We should re-enable
these in the future.

A few custom report types are skipped by configurejson2cmake (like
values of qmake CONFIG or buildParts).
These will have to be addressed a case-by-case basis if still needed.

d0911d0a92 CMake: Port the 'separate_debug_info' feature
For this, we have to uninline the separate_debug_info configure test,
because supporting the conversion of this in configurejson2cmake is not

Separate debug information can be turned on for a target by calling the
function qt_enable_separate_debug_info. For Qt's shared libraries and
tools separate debug information is generated if the
'separate_debug_info' feature is manually turned on.

a9caec4a92 CMake: Fix Ninja Multi-Config framework builds
Depends on a new bleeding edge feature in as-of-yet unreleased
CMake 3.18, that allows building macOS frameworks using the
Ninja Multi-Config generator targeting more than
one configuration.

It uses the new CMAKE_FRAMEWORK_MULTI_CONFIG_POSTFIX_DEBUG
property which tells CMake to create properly named debug artifacts
in the Multi-Config ninja file.

Without it, both debug and release artifacts would have the same
location (no _debug) postfix, so it would be unclear which file
ends up being compiled as last (the debug or release variant).
