[CMake] CXX_COMPILER_FLAGS also passed to the linker?

[Mike Jackson]

I am using the intel c++ compiler for OS X and I am trying to shutoff  
some remarks that the compiler kicks out. According to the Intel Docs  
if I pass "-wd[RemarkNum],[RemarkNum]..." to the compiler I can  
shutoff what I want.
   So I fired up ccmake and set the CMAKE_CXX_FLAGS to "-wd981" and  
then ran make. The compile proceeds file (without the remarks) until  
the link phase. The linker is dying because "d981" is being passed to  
the linker which is not right. Is this a bug in CMake or am I not  
using ccmake correctly?
