Make sure to convert absolute paths generated using the
$<TARGET_LINKER_FILE> generator expressions into relative paths.
Because prl files are generated for both modules and plugins, we need
to pass both a list of qt module locations and qt plugin locations
to QtFinishPrl.cmake, and then try to make the absolute path relative
to each passed directory.
A warning assertion is shown if we no relative path could be made,
which will cause an absolute path to be embedded. This should not
happen though.

qmake adds QMAKE_PRL_LIBS values on the link line after the currently
processed library. Because CMake adds resource object files into
QMAKE_PRL_LIBS, they end up on the link line after the library.
This causes issues on Linux with GNU ld and ld.gold, because the
linker discards symbols from the library which are then later referenced
by the object files.
Work around that by placing the path to the library directly into
QMAKE_PRL_LIBS after the resource object files.
This ensures the linker doesn't discard the symbols required by the
resource object files.
This means that each library encountered in qmake's LIBS variable will
be temporarily referenced twice in qmake's project state: once from
LIBS / QMAKE_PRL_TARGET, and once when the QMAKE_PRL_LIBS values are
added. On the link line it will appear only once though, because qmake
does library deduplication during prl file processing, which only keeps
the last occurrence.

In MSVC static build, if we build Qt with 3rdparty library (e.g. zstd),
cmake will add"zstd" (without "-l" prefix) to Qt6Core.prl. Then we
use this Qt to build a qmake project, compilation will fail due to
missing zstd.obj. Without "-l" prefix, qmake will treat "zstd" as an
object file instead of a library.
Library names in qt_module.pri and qt_lib_*_private.pri are also
missing "-l" prefix.
This is because on most compilers, CMAKE_LINK_LIBRARY_FLAG equals
"-l". But on MSVC, it is an empty string. So we should pass
"-DLINK_LIBRARY_FLAG=-l" for MSVC.
Also add "-L/path/to/library" if the library path is not in default
linker search directories. This will write un-relocatable paths to prl
files only when using 3rdparty libraries to build Qt statically. Usually
it's not a problem.
In addition, CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES is also empty on
MSVC. So The third argument of "$<FILTER>" is empty, it is an invalid
generator expression. This means no include dir will be written to
qt_module.pri and qt_lib_*_private.pri on MSVC. So only use "$<FILTER>"
when CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES is not empty.

CMake makes possible to specify a target in the target_link_library
call even if the target is not declared yet. This adds flexibility to
the target declaration arrangement. For the Qt modules we have to
restrict freedom, because of the .prl files generating. If the Qt
module depends on another Qt module, the dependecy must be declared
before the module finalizing step, otherwise this will cause invalid
records in the module .prl file.
TODO: The dependency order issue could be solved by using conditional
genex's when generating step1 .prl file. But we ask developers to
depend on Qt module targets that have been defined before their usage.

The generated object resource library depends on the Qt::Core library
because uses the functions defined in qresource.cpp. Dummy linking of
the Qt::Core to an object library has an effect only when the object
library is linked directly to the executable as a target. If we link
the object library as INTERFACE library we miss out all the objects
that need to be linked to the executable. This behavior is explained
here:
https://bit.ly/3sFWKvI
Thus, the only option to link the object library objects to the
endpoint executable is to use TARGET_OBJECTS property in genex, as
it's already done. But that means we are losing all profits that
target actually has, especially linking the object library dependencies.
The combination of both of the above methods does the job. The only
thing that looks fragile so far is order. Currently, the order we
use in the target_link_library call applies to the linker command line.
This means the object library objects must always appear before the
object library target.

When building a repository != qtbase, like qtactiveqt, QMAKE_PRL_LIBS
contained entries like Qt6Core and Qt6Widgets, meaning the linker line
would contain exactly these arguments.
When building an activeqt example with qmake, the link then failed with
"LNK1181: cannot open input file 'Qt6Widgets.obj'".
The correct entry would have been $$[QT_INSTALL_LIBS]/Qt6Widgets.obj.
Fix this by determining the full path to the import library in the first
step of the prl generation. This enables QtFinishPrlFile.cmake to
recognize Qt6Widgets as Qt module and generate the right QMAKE_PRL_LIBS
entry.

Before this change, the prl files always assumed that resource object
files are installed into $qt_prefix/lib when doing a prefix build.
That was true for qt_internal_add_resource calls, but not for
qt6_add_qml_module and qt6_target_qml_files.
Change qt_internal_record_rcc_object_files to take a new required
INSTALL_LOCATION argument. The argument takes a path relative
to CMAKE_INSTALL_PREFIX.
Modify __qt_propagate_generated_resource to save the relative path of
the generated resource source file, which will be used in the
computation of the final resource object file location.
This is needed because the Qml resource functions place the source
files in a different directory layout, e.g. .rcc vs .qmlcache
Modify qt_generate_prl_file to prepend $$[QT_INSTALL_PREFIX]/
instead of $$[QT_INSTALL_LIBS]/ for the resource install paths.
A follow up patch is done in qtdeclarative to pass the new
INSTALL_LOCATION argument from the Qml CMake functions.

The CMake build of Qt intends to improve the developer experience in
regards to static Qt builds and Qt resource files. Specifically with a
CMake build of Qt, Qt developers don't have to manually call
Q_INIT_RESOURCE anymore.
For details see the following commits
e343affd63e817ac3d684ab5432081
The last commit's implementation is incomplete though.
To ensure successful linking, each target's prl file should contain
not only the resource object files that are assigned to the target,
but also all resource object files of the target's dependencies.
To achieve that, qt_collect_libs will now recursively collect all
resource object files assigned to the QT_RCC_OBJECTS property of each
dependency.
Note this implementation is still incomplete. We do not export rcc
object file information in the CMake Targets files.
That means that when configuring qtdeclarative in a
non-top-level build, the generated Qml prl file will not
contain references to Core's mimetypes resource object file, etc.
So with the current change, only the object files that are part of the
current CMake configuration build are tracked.
Exporting the resource object files locations proves in a format
usable for prl files proves to be difficult (due to CMake not
supporting exporting genexes in random properties) and will have to be
addressed in a separate change.

That is not sufficient for non-qtbase prefix builds, where

build dir and in the prefix dir.
Detect such cases, and rewrite the absolute paths to relocatable paths

Add an abstraction over Qt::WinMain (aka qtmain.lib) and

The Core target will now link against the Startup target on all
platforms, instead of just WinMain on Windows.
The creation and linkage interface definition of the Startup target
is done at find_package(Qt6Core) time via the private call of

This will add automatic linkage of WinMain to executables marked with
the WIN32_EXECUTABLE property on Windows.
As well as the addition of the '-Wl,-e,_qt_main_wrapper' linker flag
when linking iOS executables.
Qt users can opt out of this behavior by either setting the
QT_NO_LINK_QTMAIN property or variable. This is in line with
Qt 5 behavior.
