--- Comment #2 from Don Hinton <hintonda at gmail.com> ---
Newer versions of cmake (>=3.4) have new variables you can pass to take care of
this.  So, instead of setting CC and CXX to include ccache, you can pass it to
CMAKE_<LANG>_COMPILER_LAUNCHER, e.g.:

-DMAKE_C_COMPILER_LAUNCHER=ccache
-DMAKE_CXX_COMPILER_LAUNCHER=ccache

It's a big chatty, but it'll allow you to use ccache with libcxx[abi] and run
the tests.
