Summary: This patch is an attempt to make the `find_package(FFI)` support in LLVM prefer to provide the static library version if present. This is currently an optional library for building `libffi`, and its presence implies that it should likely be used. This patch is an attempt to fix some problems observed with testing programs linked against `libffi` on many different systems that could have conflicting paths. Linking it statically prevents this. This patch adds the `ffi_static` target for this library.
See docs/CMake.html for instructions on how to build LLVM with CMake.
