[CMake] Differentiating CMAKE-driven compiles from product compiles

[Phil Smith]

For our cross-compiling, we need to set some "peculiar" compiler options. However, those options make CMake fail when it calls the compiler for CheckTypeSize, testCCompiler, and CheckIncludeFile (what I call the "CMake compiles").

Is there a way to differentiate the options passed on the CMake compiles?  I keep peering at CMAKE_BUILD_TYPE, but I don't think that's quite it.
