- Add a way to generate a FasTCConfig.cmake file so that you can use cmake without having to install it. - Add install paths for users that want to install it. - Hide all public headers in FasTC/ qualified include path, this way we know what files are public directly from the source. Also, it lets us define build-tree and install-tree include directories a lot easier.
