Summary:                    command line CXX_FLAG settings overridden by
settings in system-wide .cmake files
Description: 
KDE defines a number of compiler options that are (supposedly) required but that
include optimisation options. These settings are defined in system-wide .cmake
files like FindKDE4Internal.cmake and get applied *after* user-specified
settings have been applied. They even seem to override tweaks made directly in
CMakeCache.txt (to CMAKE_CXX_FLAGS_RELEASE or _RELWITHDEBINFO).
Even if user-specified compiler flags do make it to the list in the generated
*.make files, the KDE/system-defined options are *appended* to the list, causing
-O2 to override -O3 or -g -g3. 

Is it possible to specify the KDE/system options in such a way that they appear
at the start of the options list in the *.make files?

Steps to Reproduce: 
N/A

Additional Information: 
Not really a bug, more a question and possibly a feature request.
