Out-of-tree unit tests are not easy as it requires gtest from the LLVM source tree. Polly up to now only requires the LLVM_INSTALL_ROOT. llvm-config can be queried for the source dir, but then we need to compile gtest ourselves.

Clang has a different approach: It requires the source tree and broadly imports all cmake files such that it can use the LLVM functions to build the files.
