[llvm-dev] Embedding llvm as a git submodule in Project

[Chris Bieneman via llvm-dev]

Timo, if you want to have LLVM in-tree with your project, and your project builds with CMake, all you should need to do is call "add_subdirectory(llvm)" in the CMakeLists.txt file at the directory where the submodule gets checked out.

After the initial cmake configure pass, you should have a ./lib/cmake/llvm/LLVMConfig.cmake in the llvm build directory.  If you look at the CMake docs for find_package, you can see it's search heuristics and that if you set the CMake variable LLVM_DIR to /path/to/llvm-build-dir/lib/cmake/llvm/ then find_package should work.
