yes. With llvm 3.6 it prints something link ClangConfig.cmake not found,
but because it is not required is does not fail.

On Windows builds using KDE/Emerge clang provides cmake support, so
find_package(Clang) is required too.

I see.  On opensuse  and Windows (llvm 4.0.0svn) setting of CLang_DIR or
LLVM_DIR is not requried.

Additional on Windows the following fragment is required below
find_package(CLang)

if(CLANG_FOUND)
        include_directories(${CLANG_INCLUDE_DIRS})
        add_definitions(${CLANG_DEFINITIONS})
    endif()

I'm going add this stuff to git master.

for windows see above.

As long as we are using testcases only it should be in unittests to
reduce hidden interferences. Later with more experience and having llvm
support build into main umbrello we can move this up.
