CMake: Generate qmake .prl files This commit also adds a qt_finalize_module function that is called for every Qt module after all link dependencies have been added. Change-Id: I489d188d05e368208a8a62828bb12fb395df54bc Reviewed-by: Alexandru Croitor <alexandru.croitor@qt.io>

# Finish a preliminary .prl file.
#
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.

# - Strips version number suffixes from absolute paths, because qmake's lflag
# merging does not handle them correctly.
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.

CMake: Write object libs of Qt resources to .prl files Since commit e343affd634 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.

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.
