That's unfortunate.  Looks like the test in CMakeTestCCompiler.cmake sucks.

There are a couple ways to trick it, though.  For example, you can undefine __cplusplus for just that test by adding -U__cplusplus before CMakeTestCCompiler.cmake is loaded.  Another way that should probably work is to set CMAKE_C_COMPILER_WORKS so it skips the test altogether (perhaps cmake -DCMAKE_C_COMPILER_WORKS=YES or some variation thereof).

Awesome to see the progress.  We have had a couple to-do's related to compiling all of BRL-CAD with a C++ compiler for a long time.

Cheers!
