> Generated header files, such as protobufs are currently generated all at once in the CMake build system:
> https://github.com/apache/mesos/blob/db8b0f16c1c8c6e683a4b788262f307a8bc218e0/cmake/MesosConfigure.cmake#L77-L80
> This means, if a protobuf is changed, the CMake build system will not regenerate new protobufs unless you delete the generated {{/include}} directory.
> ----
> Should be a trivial fix, as the CMake protobuf functions merely need to depend on the input file:
