I tried to make this an environment variable that clang++ could take,
but still:

$ LIBCXXABI_LIBCXX_INCLUDES=/mnt/compil/llvm-toolchain-7-7/libcxx/include /mnt/compil/llvm-toolchain-7-7/build-llvm/bin/clang++    -g -O2 -fdebug-prefix-map=/mnt/compil/llvm-toolchain-7-7=. -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 -DLLVM_NO_OLD_LIBSTDCXX  -std=c++0x   -o CMakeFiles/cmTC_b2902.dir/src.cxx.o -c /mnt/compil/llvm-toolchain-7-7/libcxxabi/build/CMakeFiles/CMakeTmp/src.cxx -v
