Bumps cmake minimum version to 3.7 for version comparison operator. Previously the Clang cmake project version strings were used. These are not defined if the clang cmake project has not been loaded. We should use CMAKE_CXX_COMPILER_VERSION to check the version when only the compiler binary is redirected and the project files are not available. Also adjust device libs lookup logic to handle multiple paths in CMAKE_PREFIX_PATH. Change-Id: I67b6958d8241685cd6c3a0af68507c9fdc6331ef
