[CMake] Not getting the CXX/CC I requested with v 2.4.5

[Pugmire, Dave]

Hi,
I'm experiencing some weirdness trying to configure on a cray.
I do the following:
env CXX=g++ CC=gcc ./bootstrap
configure seems to report that it's using g++ to do the checks.
However, when I do a make, it's using a different compiler.

>> make

I'm new to cmake, so I'm not sure where to begin looking. However, grepping around, I see that the file Source/kwsys/CMakefiles/cmsys.dir/build.make is referencing the wrong compiler:

	/opt/xt-pe/2.0.26quadcore1/bin/snos64/CC   $(CXX_FLAGS) -o Source/kwsys/CMakeFiles/cmsys.dir/Directory.o -c /tmp/work/pugmire/visit-cnl/visit-loginnode/cmake-2.4.5/Source/kwsys/Directory.cxx


and I'm not sure what is generating this line.
Anyone seen this before? Any ideas on how to fix this?

Thanks,
Dave
