58a7e4f0bc CMake: Implement workaround for failing linux static builds
In static builds, due to our CMake design for auto-linking plugins
being incorrect we sometimes cause link failures on Linux in leaf
modules, because the link line order is incorrect.

So far such failures were fixed by explicitly modifying the order of
libraries on the link line in each failing CMake project.

This proves to be problematic because the failures appear in seemingly
random integrations that don't even touch the build system parts.

Until we fix the design, another less performant but more
general / safe way is to increase the link interface multiplicity,
which causes a cycle of libraries to be repeated more than 2 times
on the link line, thus giving the ld linker more chances to figure out
which symbols are needed for linking.

Implement this for Linux static builds to avoid random integration
failures for people that know nothing about this issue.

The link multiplicity for all qt modules is increased to 3, thus
QtGui would be repeated 3 times on the link line of each dependent
library. The value is also configurable via the
QT_LINK_CYCLE_MULTIPLICITY cache variable.

b73809f30c CMake: Fix incorrect paths in build instructions message
When doing a top-level build,
QT_BUILD_INTERNALS_RELOCATABLE_INSTALL_PREFIX is not set in the
top-level scope. There's no point really in using the relocatable
path anyway, given this will only be displayed once when either
configuring qtbase or qt6.

Just use CMAKE_INSTALL_PREFIX directly.

a7162704c8 CMake: Fix installation location of plugins in static builds of Qt
For static builds of Qt we installed the plugins into the lib
directory. However, they are expected in the plugins directory tree.

This happens, because we pass a value of an uninitialized variable to
ARCHIVE DESTINATION in the qt_install call in qt_internal_add_plugin,
and CMake defaults to "lib".

This flaw was introduced in b42feb02ce with the following intent:
"This patch also changes add_qt_plugin() to use the value provided in
INSTALL_DIRECTORY for ARCHIVE_INSTALL_DIRECTORY if no value is provided
for the latter."

The patch changed the value of arg_ARCHIVE_INSTALL_DIRECTORY but
missed to set the variable archive_install_directory, which is
actually used in the qt_install call.

We now directly set archive_install_directory and remove the unused
archive_install_directory_default variable.

dde11715d3 CMake: Temporary workaround for static top-level Qt builds
Because find_package usually creates targets in a local scope,
qt_generate_prl_file fails to generate a .prl file that has
references to generator expressions like
"$<TARGET_FILE:Freetype::Freetype>" which references targets
that are not found in that specific scope (e.g Freetype target is
present in qtbase scope, but not qtsvg scope).

This happens in static top-level Qt builds, and thus fails the
configuration. While we try to figure out how to fix this adequatly,
don't generate .prl files in such a configuration.

2a767ab4bb CMake: Fix libraries in qt_lib_XXX_private.pri files for NMC
qmake_use.prf understands the _DEBUG and _RELEASE suffixes for
QMAKE_LIBS_XXX entries. The CMake configuration "Debug" is considered
for the _DEBUG entries, "Release" and "RelWithDebInfo" for _RELEASE.

The qt_lib_XXX_private.pri files are now generated in multiple steps:
1. The QT_LIBS_XXX information is generated per $<CONFIG> and written to
   .cmake files.
2. A preliminary qt_lib_XXX_private.pri file is generated, containing
   only configuration-independent data.
3. A custom command runs the QtGenerateLibPri.cmake script that combines
   the files from step 1 and 2 into the final qt_lib_XXX_private.pri
   file.

The same is done for mkspecs/qmodule.pri.

To be able to trigger custom commands from header modules, which are
interface libraries, we introduce one XXX_timestamp ALL target per
header module that creates a timestamp file. To that XXX_timestamp
target we add the pri file generation target as dependency.

CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT might be empty on the
first configuration, but because QtBuildInternalsExtra sets the
CMAKE_INSTALL_PREFIX, a second reconfiguration of a test would

After some further consideration, there's no need to set the local

opted out).

This makes sure that a reconfiguration of a test doesn't suddenly
install into the Qt prefix again.

dc26b30acd CMake: Protect against Qt toolchain file recursive inclusion
Three different people have encountered the issue that calling
calling qt-cmake on a project prints 1000 inclusion lines of the same
qt toolchain file, and then CMake bails out saying can't find the
CMAKE_MAKE_PROGRAM Ninja.

This happened because people accidentally called qt-cmake to configure
qtbase (instead of just cmake), which created a toolchain file that
chainloads itself recursively.

Error out when configuring qtbase, and when using the generated
toolchain file in the case when it would try to include itself.

The solution is to remove the qtbase CMakeCache.txt file, and
configure qtbase again, so it generates a proper qt.toolchain.cmake
file.

If somebody feels enthusiastic, they can move the check into the
qt-cmake and qt-cmake-private shell scripts, and error out before the
qtbase/CMakeCache.txt is polluted with the wrong toolchain file.
That is left for people that feel more comfortable with bash and batch
scripting.

we need to provide the information about libfoo in the qt_lib_XXX.pri
files.

Also, we now generate qt_ext_XXX.pri files for bundled 3rdparty libs.

b3e01d608e CMake: Use custom install script to support Ninja Multi-Config builds
Calling cmake --install . only installs a single configuration.

To install both debug and release artifacts, the install
invocation needs to be done for each configuration.

To keep the Coin instruction code simpler, delegate the looping
over configurations to a custom CMake script, and use it in the
Coin instructions.

Replace all cmake --install calls in the instructions with calls
to either call_host_install.yaml or call_target_install.yaml.

The path to the script depends on whether we are building
qtbase or another module. In the former case the script should
be called from the build dir, otherwise from the install dir.

The other distinction is whether the host or target env prefix
needs to be added.

f240d94f14 CMake: Install non-main-config tools and executables to a subdir
When using Ninja Multi-Config, we don't want to install a "Release"
moc.exe, and then override it with a "Debug" moc.exe.

Because it doesn't seem possible to exclude installation of targets
per configuration, put the non-main configuration tools into
configuration specific subfolders like "bin/Debug", so no overriding
happens upon installation.

Introduce a new function qt_get_install_target_default_args() which
returns install destination arguments for consumption in qt_install()
calls. The function adds the config-specific suffix to the destination
for the appropriate configs.

Each call to qt_install *adds* new rules for installation,
which means that export registration needs to happen only on the first
call.

Make sure qt_add_tool doesn't ask qt_add_executable to install
yet again, to create duplicate rules.

Apply the same install arguments logic to qt_add_executable calls.

06b148074a CMake: Allow using single config generators after building with NMC
Where NMC is the CMake Ninja Multi-Config generator.

The first use case is to allow building standalone tests with one
configuration even if Qt was build with multiple configurations.

Another use case is for regular Qt consumers that might use the
generated qt-cmake shell script which does not have the generator
specified (as opposed to qt-cmake-private).

Another detail is to use the first configuration from the initial
Qt configurations list (CMAKE_CONFIGURATION_TYPES) when building
standalone tests with a single config generator, so that it doesn't
default to Debug, but rather to the provided first configuration.

This matches qmake behavior, where on Windows with a
debug_and_release configuration, tests are still built against
release.

bf315c5526 CMake: Make build system of installed Qt more relocatable
Aka handle CMAKE_INSTALL_PREFIX in a more relocatable way.

The following story inspired this change.

If a user wants to build a Qt repo into a different install prefix
than the usual Qt one, this will fail configuration because we
look for various things like syncqt, qdoc, etc relative to
CMAKE_INSTALL_PREFIX, which will now point to a different location
where none of the above tools are located.

The intent for such a use case is to support building Qt packages with
Conan, which sets a random install prefix when configuring a repo.

The idea is to derive the qt prefix dynamically from the
QtBuildInternals package location. Essentially it's a reverse relative
path from the QtBuildInternalsConfig.cmake file to the install prefix
that was specified when initially configuring qtbase.

Once the dynamic prefix is computed (so we know where the possibly
relocated Qt is), we can find tools like syncqt and qdoc.

This is an initial attempt to support a use case like that.

More design work will probably needed in case if tools / libs need to
be found in a location different than the Qt install prefix (so
support for multiple install prefixes / search paths).

An example of such a case would be when building qtdeclarative and
qtquickcontrols2 as Conan packages in one go. Most likely the
qmltyperegistrar tool will be located in the random install prefix
set by Conan, so building qtquickcontrols2 might fail due to not
finding the tool in the original Qt install prefix.

As to the implementation details, the change does the following:
- Dynamically computes and sets the
  QT_BUILD_INTERNALS_RELOCATABLE_INSTALL_PREFIX variable when
  find_package()'ing QtBuildInternals. It's an absolute path
  pointing to where the relocated Qt is.

- When building qtbase this variable is not yet available (due
  to QtBuildInternalsExtra not existing), in that case we set
  the variable to the absolute path of CMAKE_INSTALL_PREFIX
  (but only for the initial qtbase configuration).

- Remove QT_BUILD_INTERNALS_ORIGINAL_INSTALL_PREFIX which was used
  for standalone tests purposes. It's not needed now that we compute
  the location of the Qt prefix dynamically.

- The Unixy qt-cmake and qt-cmake-private shell scripts now
  use a relative path to find the toolchain file we created.

- The toolchain file also dynamically computes the location of the Qt
  packages, and adds them to CMAKE_PREFIX_PATH.

- A lot of existing CMAKE_INSTALL_PREFIX uses are replaced with
  QT_BUILD_INTERNALS_RELOCATABLE_INSTALL_PREFIX. This includes finding
  tool locations, mkspecs dir, path environment setup for tools, etc.

- Some places still use CMAKE_PREFIX_PATH in the following cases
  - When determining paths while configuring qtbase (valid cases)
  - When I wasn't sure what the behavior should be, so I left them
    as-is (an example is documentation generation, do we want to
    install it into the random Conan prefix, or into the main prefix?
    Currently it installs in the random prefix).

Note that relocating a Qt installation does not work for non-prefix /
non-installed builds, due to hardcoded paths to include directories
and libraries in generated FooTargets.cmake files.
