[CMake] cmake with intel compilers

[Burlen Loring]

hmmm, I was a bit hasty in concluding that the issue has gone away in 
newer releases. on another system, I have the issue with cmake 2.8.8. 
The intel compiler version there is 11.1. On this system if I don't 
include $INTEL_ROOT/include/intel64 explicitly , gcc's xmm intrinsics 
are found causing errors (typical error follows).  Examining the output 
of make VERBOSE=1, I'm not seeing any reference to the path containing 
either gcc or intel xmm intrinsics. Is this a cmake issue? or perhaps a 
configuration issue with the intel compiler on this system?

/usr/lib64/gcc/x86_64-suse-linux/4.3/include/xmmintrin.h(105): error: 
identifier "__builtin_ia32_addss" is undefined
     return (__m128) __builtin_ia32_addss ((__v4sf)__A, (__v4sf)__B);

Thanks Leif, this system uses environment modules to configure the intel 
compiler, they are loaded. I searched for the script you mention but 
it's not present on this system. There are no *INCLUDE* env vars set, 
however CC,CPP,CXX,F90  etc are set correctly to point at the intel 
compilers.
