Niko,
You have to add a couple of things to some CMake files.
1) Add the component(s) to the top level CMakeLists.txt. For example
https://github.com/drmpeg/gr-atsc3/blob/master/CMakeLists.txt#L77
2) Add the libraries to the linker in lib/CMakeLists.txt. For example:
https://github.com/drmpeg/gr-atsc3/blob/master/lib/CMakeLists.txt#L39
