Sounds Ok, if that works on Windows as well :) I guess made error as I tried 
that last time and it seemed not to work, that was the reason I tried it with 
the CMAKE_C_FLAGS stuff which worked out of the box. Does LDFLAGS be honored, 
too, if set on Windows, on Linux it seems? And what's up with CPPFLAGS, 
should I mix them into the CFLAGS/CXXFLAGS or are they honored in addition on 
Linux/Windows, seems not be the case for C++?

Other question: Are any flags added to the given default via environment? Our 
current Buildsystem dictates debug/release/profiling/... buildtypes by just 
setting the env vars to the appropriate values, will this work out of the box 
by running cmake + (make|nmake) while this vars are set or will cmake still 
add it's ideas of debug/release flags?

Btw., thanks already for the help, makes my life easier for linux, seems I 
just made stupid error that I thought the flags would be ignored there :)
