CMake build with Clang may fail due to installation path

[jibsen]

I have been trying to track down an issue with building Squash using Clang on AppVeyor, and I believe the problem was that Clang is installed to a path containing spaces (C:\Program Files\LLVM).

More specifically, when the path contains spaces, CMake ends up invoking clang++ with the short name C:\PROGRA~1\LLVM\bin\CLANG_~1.EXE, but clang++ only behaves like a C++ compiler if its name is clang++, so it does not link with the standard C++ libraries.

If I copy the LLVM folder to C:\LLVM (and add that to the path), the build works.
