Wow

At I did something before (at
https://github.com/okuoku/bsd-cxx-runtime ), IIRC, CMake didn't set
proper lit.py path for it.
So if you like to use lit.py to testing the build:

1) checkout llvm and specify its utils/lit/lit.py fullpath for libc++
CMake configuration (as -DLIT_EXECUTABLE=/PATH/TO/utils/lit/lit.py)
2) Arrange libc++ test/lit.cfg to add FreeBSD configuration (like:
https://github.com/okuoku/libcxx/commit/abcfa43d5e6360dc311db63320a9d940e0c21ed1#diff-11
)

Good luck!
