Joerg Bornemann 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.

# Finish a preliminary .prl file.

# - Replaces occurrences of the build libdir with $$[QT_INSTALL_LIBDIR].
# - Strips version number suffixes from absolute paths, because qmake's lflag
# merging does not handle them correctly.

# This file is to be used in CMake script mode with the following variables set:
# IN_FILE: path to the preliminary .prl file
# OUT_FILE: path to the final .prl file that's going to be installed
# QT_BUILD_LIBDIR: path to Qt's libdir when building (those paths get replaced)
# LIBRARY_SUFFIXES: list of known library extensions, e.g. .so;.a on Linux
