[CMake] add_definition??

[klaas.holwerda]

Hi,

I use ADD_DEFINITIONS( ${wxWidgets_DEFINITIONS} ) to add flags for compilation like this:

     set( wxWidgets_CXX_FLAGS ${wxWidgets_CXX_FLAGS}
         -D__WXMSW__ -D__GNUWIN32__ -D__WIN95__
         -fexceptions -fno-pcc-struct-return
         -fstrict-aliasing
         -Wall    #all warnings
         -Wno-unused-variable
          )

Now a user complains that those flags are added to CXX_FLAGS as well as RC_FLAGS .
The first is right, the second is a problem for the resource compiler windres.exe used in codeblocks 
IDE.

What is the right way to set compiler flags for cpp sources and other flags for the resource compiler?

Or are the generated makefiles not correct??

Thanks,

Klaas
