Re-opening.

Cmake sets CC and CXX during config time so users can run configure, or cmake in this case, with the same compiler (see discussion by Brad King here: https://gitlab.kitware.com/cmake/cmake/issues/16356).

Since these are the only environment variables set, we can fix the bots by passing CMAKE_(C|CXX)_COMPILER to add_custom_command.
