bae96f1792 CMake: Fix generation of prl files for non-qtbase modules
Previously we determined if a library represented by an absolute path
is a Qt module by checking if it's located in the build dir of the
current repo.

That is not sufficient for non-qtbase prefix builds, where
a Qt module might link against both a module in the current
build dir and in the prefix dir.

Detect such cases, and rewrite the absolute paths to relocatable paths
(either framework flags or paths starting with $$[QT_INSTALL_LIBS].

This should fix building examples with qmake that use QtQuick.

736408880b CMake: Do not prepend -l to libs starting with dash in prl files
For example, we must not prepend -l to -pthread, -framework and -lfoo.

9c0f448f5a CMake: Fix generated content of prl files (again)
Apply the same kind of transformations to the contents of the prl
files as we do for pri files. Mainly, transform system library paths
that are absolute, into link flags to make them relocatable across
systems.

Also change the Qt frameworks to be linked via the -framework flags
instead of via absolute paths.

Implementation notes

Move the common required functions for both QtFinishPrlFile and
QtGenerateLibPri into a common QtGenerateLibHelpers.cmake file.

Make sure it's listed as a dependency for the custom commands.
Also make sure to pass the necessary input values like possible
library prefixes and suffixes, as well as the link flag.

9d55d6b45b CMake: Fix building debug apps with qmake on Windows
Our CMake build system only generated working .prl files for
the Release configuration in debug_and_release.

This caused a linking failure when building a Widgets example that
links against qtmain, specifically

qtmaind.lib(qtmain_win.cpp.obj) : error LNK2019: unresolved external
symbol __imp_CommandLineToArgvW referenced in function WinMain

The symbol is located in shell32.dll, which was not linked in, because
there was no qtmaind.prl file.

The fix to generate per config prl files is a bit complicated, because
add_custom_command does not support generator expressions in OUTPUT
and DEPENDS.

Instead we pre-generate 2 files per config, one with the preliminary
prl file content and another file that contains the final prl file
path (via generator expression).

Then we iterate over all configurations and create custom commands
with well known paths, and the final prl file is created by the script
called by the command.

4ab5432081 CMake: Write object libs of Qt resources to .prl files
Since commit e343affd63 we're creating object libraries for Qt
resources in static libraries. Those must be reflected in the
generated .prl files for static builds of Qt.

In qt_add_resource, we now calculate the install locations of the
object files of rcc-generated C++ files and save them in the target
property QT_RCC_OBJECTS. This property is then passed to
QtFinishPrlFile to write the object file paths to the .prl file.

bd2a14ff98 CMake: Do not use $$[QT_INSTALL_LIBS/get] in generated .prl files
We do not support building with qmake from the build directory in prefix
builds. Therefore we can just use the standard QT_INSTALL_LIBS property
instead of the /get variant.

c254254c55 CMake: Fix qmake mixing for framework builds
Include headers in .pri files should point to the framework Headers
dirs.

The module name in the .pri file is not versioned when it's a bundle.

Paths to system frameworks in .prl files should instead be replaced
with -framework Foo flags.
