CMake Error in arrows/kpf/yaml/CMakeLists.txt

[linus-sherrill]

I am getting the following CMake error when configuring KWIVER with KWIVER_ENABLE_KPF on, but not when it is off. This is done on current master branch.

-- Configuring done
CMake Error in arrows/kpf/yaml/CMakeLists.txt:
  Target "kpf_yaml" INTERFACE_INCLUDE_DIRECTORIES property contains path:
      "/disk2/projects/KWIVER/kwgitlab/source/arrows/kpf/yaml/include/yaml-cpp"
 which is prefixed in the source directory.
-- Generating done

If I make the following change, converting PUBLIC to PRIVATE, the problem goes away. As far as I can tell, nobody else is having this problem.
