But isn't cmake going to pick up the env variable and then tack that  
onto the CMAKE_CXX_FLAGS during cmake time? It does when you set the  
compiler this way. export CXX=icc and then run cmake and you compiler  
is now intel's c++ compiler.

    What problems does having the -fmessage-length=0 flag in a  
makefile cause? I have it defined whenever the compiler is gcc and  
presently I don't seem to have issues. I am just curious about what I  
might run into on other platforms where this may become an issue?

Thanks.
