# Building in an incomplete setup requires setting CMAKE_*_COMPILER_WORKS,
# as CMake fails to probe the compiler. This case also requires
# setting CMAKE_CXX_COMPILER_TARGET, as LLVM's heuristics for setting
# the triple fails when CMake hasn't been able to probe the environment.
# (This is what one has to do when building the initial libunwind/libcxx
# for a new toolchain.)
