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.

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.

Ugly fix for handling QT_SOURCE_TREE
QT_SOURCE_TREE is a variable that is set in qtbase/.qmake.conf.
In qtbase, it's used throughout various
projects to find cpp sources when building standalone tests (among
other things).
Everything works fine with qmake, because even if qmake is invoked
on the tests subfolder, qmake searches up the source directory tree
until it finds a .qmake.conf file, and uses that.
When building qttools with qmake, the qdoc project expects
to have a QT_SOURCE_TREE value, but it's not actually set in the
qttools/.qmake.conf file, so the generated include paths that use
that value are incorrect. Curiously the build still succeeds.
Now in CMake land we replaced QT_SOURCE_TREE with
CMAKE_SOURCE_DIR, but that does not work properly when doing a
standalone tests build, because the project in that case is the
tests one, and not the qtbase one, so configuration fails in a
developer build when trying to configure some private tests.
So far I've found that only qtbase actively uses this value.
A temporary fix is to save the qtbase source directory into a
QT_SOURCE_TREE variable inside the generated
BuildInternalsExtra.cmake file.
The pro2cmake script is changed to handle presence of QT_SOURCE_TREE
in a qrc file path. This is handled by finding the location of a
.qmake.conf file starting from the project file absolute path.
This is needed to stop the script from crashing when handling
the mimedatabase test projects for example.
The change also regenerates the relevant failing test projects, and
thus standalone tests (when doing developer builds aka private_tests
enabled) now configure and build successfully.

CMake: Fix handling of CMAKE_FIND_ROOT_PATH and CMAKE_PREFIX_PATH
While trying to implement the 'host artifact reuse' Coin instructions
change, a bug surfaced where the qemu configurations didn't find
the host tools and instead tried to use the cross-compiled tools
while building qtbase, which failed due to not finding the
runtime linker (another unsolved issue).
Before the host artifact reuse change, the host tools were found
successfully.
The difference that caused the issue is that the target install prefix
was a direct subfolder of the host prefix.
host - /home/qt/work/qt/install
target - /home/qt/work/qt/install/target
Before the host reuse change the install prefixes were as follows
host - /home/qt/work/qt/install/host
target - /home/qt/work/qt/install/target
While looking for the Qt6CoreTools package, we temporarily set
CMAKE_FIND_ROOT_PATH and CMAKE_PREFIX_PATH to contain first
'/home/qt/work/qt/install' and then '/home/qt/work/qt/install/target'.
CMake then reroots the CMAKE_PREFIX_PATH values onto values in
CMAKE_FIND_ROOT_PATH, making an MxN list of prefixes to search.
Rerooting essentially means concatenating 2 paths, unless the
considered prefix is a subfolder of the root path.
What happened was that the first considered value was
'/home/qt/work/qt/install/home/qt/work/qt/install', a non-existent
location that gets discarded.
The second considered value was '/home/qt/work/qt/install/target.
The second value is the result of seeing that
'/home/qt/work/qt/install/target' is a subfolder of
'/home/qt/work/qt/install' and thus the root path is stripped.
All of this is done in cmFindPackageCommand::FindConfig() ->
cmFindCommon::RerootPaths.
The behavior above caused the target tools be found instead of the
host ones.
Before the host reuse change, both of the initial constructed prefixes
were discared due to them not existing, e.g.
'/home/qt/work/qt/install/target/home/qt/work/qt/install/target'
and '/home/qt/work/qt/install/host/home/qt/work/qt/install/host'
One of the later prefixes combined CMAKE_FIND_ROOT_PATH ==
'/home/qt/work/qt/install/host' + CMAKE_PREFIX_PATH == '/' resulting
in '/home/qt/work/qt/install/host/' and this accidentally found the
host tools package.
We actually stumbled upon this issue a while ago when implementing Qt
5.14 Android CMake support in 52c799ed4425076df4353c02950ea1444fe5f102
That commit message mentions the fix is to add a "lib/cmake"
suffix to the PATHS option of find_package().
This would cause the subfolder => strip root behavior mentioned
above.
So finally the fix.
First, make sure not to append QT_HOST_PATH in the toolchain file,
there shouldn't be any need to do that, give that we temporarily set
it when looking for Tools packages.
Second, recreate the subdir scenario in the Qt toolchain file by
setting CMAKE_FIND_ROOT_PATH to the current (relocated) install
prefix as usual, but also setting CMAKE_PREFIX_PATH to a new value
poining to the CMake directory.
Aka '/home/alex/qt' and '/home/alex/qt/lib/cmake'.
Third, when a QT_HOST_PATH is given, save 2 paths in the generated Qt
toolchain: QT_HOST_PATH and QT_HOST_PATH_CMAKE_DIR. There are the host
equivalents of the target ones above. Use these values when looking
for host tools in Qt6CoreModuleDependencies.cmake, again facilitaing
the subdir behavior.
Note these are currently absolute paths and are not relocatable.
We'll have to figure out if it's even possible to make the host path
relocatable.
Finally as a cleanup, look for the Qt6HostInfo package in QtSetup
strictly in the given QT_HOST_PATH, so CMake doesn't accidentally find
a system Qt package.

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.
