Joerg Bornemann d6e41abd62 CMake: Handle -D, -I, -F and -L configure arguments
Introduce new CMake variables and map
-D to QT_EXTRA_DEFINES,
-I to QT_EXTRA_INCLUDEPATHS,
-L to QT_EXTRA_LIBDIRS,
and -F to QT_EXTRA_FRAMEWORKPATHS.

Those variables only affect the Qt build, not user projects.

Fixes: QTBUG-85878
Change-Id: I229df2eed1505a2619068d0d32975962b052569a
