We need to investigate the llvm cmake details first. See below.

On opensuse 13.1 where I compile umbrello I get on umbrello configure.

-- Found LLVM 3.6.1
-- Using LLVMConfig.cmake in: /usr/share/llvm/cmake

It looks that the llvm-devel package contains all related stuff for
finding clang. You have the llvm-devel installed ?

The question is if this is available on all supported platforms (linux,
windows, mac) and distributions ?
If the answer is yes, we do not need any specific stuff on umbrello side.

BTW: Also there are cmake specific docs at 
http://www.llvm.org/docs/CMake.html, which may give additional answers.
