80271e8280 Improve qmake parser debug output in pro2cmake
Override the default debug actions to be decorated with proper
indentation for easier reading.

The setup only has to be done once, and not on each QMakeParser
creation.

0425ee0610 Change the default enabled AUTOGEN tools list to contain only moc
Before this patch we enabled AUTOMOC, AUTORCC, AUTOUIC for all targets
that did not opt out.

Aside from being wasteful from a performance point of view,
this also caused issues when trying to build qtimageformats which
does not depend on Widgets which is the package that exposes uic.

To avoid this, enable only AUTOMOC for all targets by default, and
UIC and RCC can be opted in via the ENABLE_AUTOGEN_TOOLS option.

To facilitate this some refactoring had to be done, like moving some
common setup for all autogen tools into a separate call, and making
sure that extend_target understands the autogen options, because some
ui files are only added conditionally.

Also the conversion script has been adapted to output the
ENABLE_AUTOGEN_TOOLS option whenever a .pro file contains at least
one FORMS += foo assignment.

Note that we don't really use AUTORCC while building Qt, so nothing
opts into that at the moment.

c7fd10a022 Allow building the tests directory as a standalone CMake project
At the moment, Coin builds tests as a separate qmake invocation
against an installed Qt. We need to support the same with CMake.

Change the tests subdirectory to be a standalone CMake project when
CMake does not detect an existing QtTest target while processing the
subdirectory. If the target exists, it means we are building the whole
repo, if the target does not exist, we need to call find_package
to find the installed Qt.

Refactor and move around a few things to make standalone tests build
successfully:
- add a new macro to set up paths to find QtSetup
- add a new macro to find all macOS frameworks
- add a new macro to set up building tests
- add a new macro that actually builds the tests
- export the INSTALL_CMAKE_NAMESPACE value into the BuildInternals
  Config file
- export the CMAKE_BUILD_TYPE value, because a test project doesn't
  have a .git subdir and thus defaults to be built in Release
  mode, even though qtbase might have been built in Debug, so to
  avoid the mixing, the propagate the build type
- stop overriding INSTALL_CMAKE_NAMESPACE and
  QT_CMAKE_EXPORT_NAMESPACE inside QtSetup if they are set, because
  the tests project doesn't specify a major version, and if we
  override the values, the moc / uic targets don't get the correct
  major version prefix and configuration fails

76f5b784ce Fix the fix to correctly handle comments in multi-line assignments
The previous fix where the Grammar comment style was changed to
remove the newlines was incorrect, because if you have

 foo=1#comment
 bar=2

after the Grammar comment ignoring, it would transform into

 foo=1bar=2

which will clearly fail to parse, so the new line has to stay.

But we would still have the following case which would fail:
 foo=a \
 # comment
 b

Apparently qmake things that's the equivalent of
foo=a b

but the grammar parses it as
 foo=a \
 \n (newline)
 b

Thus the parsing fails because there's a newline and then some
weird 'b' token which the grammar does not expect.

The best fix I found is to preprocess the source, to remove
completely commented out lines.

So:
 foo=a \
 # comment
 b

gets transformed into

 foo=a \
 b

e4b8c488bd Improve configure2cmake to find_package only in certain conditions
It doesn't make much sense to look for X11 related packages on
macOS and Windows by default. Usually they would not be there, and
as a result the configuration step would show a long list of scary
not found packages, and also eat precious configure time.

Change the conversion script to allow putting conditions around
generated find_package calls.

These conditions can be manually set in the conversion script
library mapping, using the emit_if argument,
which we do for the X11 and Wayland related packages.

They are also computed by checking which features use a given library,
and if the feature is protected by a simple emitIf condition like
config.linux, the relevant library find_package call will be protected
by the same condition.

If a developer still wishes to look for all packages, they can define
the CACHE variable QT_FIND_ALL_PACKAGES_ALWAYS to ON.

The relevant configure.cmake files are regenerated in this patch.

9542e78525 Use the qt_build_repo() macros for building qtbase as well

All child Qt modules like qtsvg should use
find_package(Qt5BuildInternals) or
find_package(Qt5 COMPONENTS BuildInternals) in the their
top level CMakeLists.txt.
This will make the qt_build_repo() macros available.

For qtbase we slightly cheat, and specify a CMAKE_PREFIX_PATH
pointing to the source folder that contains the BuildInternals
package.

For the other modules we actually use a configured and installed
package Config file.

This change moves variables that used to be written into the
QtCore Config file into the BuildInternals package. This way
things that are relevant only for building additional Qt modules
does not pollute the QtCore package.

c097256ee4 Encapsulate commands for building other repos into two macros

To make it cleaner, introduce two new macros called

should be called in a child repo like qtsvg, right after
a find_package(Qt5) call, and the second one at the end of the
repo top-level CMakeLists.txt file.

In order for the macros to work, extract some of the variables
which were set in Qt5Config into Qt5CoreConfig instead. This
makes sure that it works also for find_package(Qt5Core) calls.

02a015375a Implement developer / non-prefix builds
A non-prefix build is a build where you don't have to run
make install.

To do a non-prefix build, pass -DFEATURE_developer_build=ON when
invoking CMake on qtbase. Note that this of course also enables
developer build features (private tests, etc).

When doing a non-prefix build, the CMAKE_INSTALL_PREFIX cache variable
will point to the qtbase build directory.

Tests can be run without installing Qt (QPA plugins are picked up from
the build dir).

This patch stops installation of any files by forcing the
make "install" target be a no-op.

When invoking cmake on the qtsvg module (or any other module),
the CMAKE_INSTALL_PREFIX variable should be set to the qtbase build
directory.

The developer-build feature is propagated via the QtCore Config file,
so that when building other modules, you don't have to specify it
on the command line again.

As a result of the change, all libraries, plugins, tools, include dirs,
CMake Config files, CMake Targets files, Macro files, etc,
will be placed in the qtbase build directory, mimicking the file layout
of an installed Qt file layout.

Only examples and tests are kept in the separate module build
directories, which is equivalent to how qmake does it.

The following global variables contain paths for the
appropriate prefix or non prefix builds:
QT_BUILD_DIR, QT_INSTALL_DIR, QT_CONFIG_BUILD_DIR,
QT_CONFIG_INSTALL_DIR. These should be used by developers
when deciding where files should be placed.

All usages of install() are replaced by qt_install(), which has some
additional logic on how to handle associationg of CMake targets to
export names.

When installing files, some consideration should be taken if
qt_copy_or_install() needs to be used instead of qt_install(),
which takes care of copying files from the source dir to the build dir
when doing non-prefix builds.

Tested with qtbase and qtsvg, developer builds, non-developer builds
and static developer builds on Windows, Linux and macOS.

400f94109d CMake: Wrap DBus1 find_package call to fix xproto not being picked up
DBus1 (1.12) configuration file breaks PKG_CONFIG environment
variables and will thus prevent other libraries to be picked up
by pkgconfig. Main sympthom is that xproto is not getting picked
up anymore, which results in hundreds of lines of warnings about
this being printed.

Work around that by wrapping the call to find_package(DBus1) and
restoring the environment.

263af45b4c Move build and test instructions from coin to qtbase
That way we can update instructions without waiting for
Coin update.

The patch contains invalid test instructions, but as
cmake port is not yet able to run tests it should not
matter.

bc4687f5bb Keep "special case" modifications when regenerating project files
The pro2cmake.py file is now smarter, and can reapply "special case"
modifications after regenerating a CMakeLists.txt file.

This substantially lowers the maintenance burden when regenerating
many files at once.

See the special_case_helper.py file for details on how it works.

Make sure to commit the generated .prev_CMakeLists.txt file alongside
your CMakeLists.txt changes.

To disable the preservation behavior, you can pass -s or
--skip-special-case-preservation to the script.

To keep around temporary files that are created during this process,
you can pass -k or --keep-temporary-files.

To get more debug output, pass --debug-special-case-preservation.

80e0c615a9 CMake: pro2cmake.py: Separate library extraction logic from writing out data
Separate the logic to find all used libraries from the code that writes out
the link_library information into the CMakeLists(.gen)?.txt files.

This patch will remove some "PUBLIC_LIBRARIES Qt::Core" from generated files.
This is due to us handling some Qt libraries in special ways in some of our
add_qt_* helpers. These special libraries were added to the LIBRARIES section,
but actually they should be added to the PUBLIC_LIBRARIES section instead. Do
so now, so that the newly generated files do not break things again.
