Add CMake config using pkg-config internally

- MoveIt cannot make a new release right now with our bugfix due to people constraints
- We cannot roll back due to project constraints
- This adds a cmake config that internally uses the pkg-config. This will be replaced in the future with one with proper CMake targets
