It looks you already know a better way, but just in case, a
straightforward way to do this is using out-of-source builds, one runs
configures cmake with two seperate build directories (e.g., build/gl,
build/gles) enabling GLES on the latter, and then its simply a matter of
doing 

  make -C build/gl
  make -C build/gles
