Hello,
Yes, main reason is I had to hack FindProtobuf.cmake to make our existing
project compile.
Also since I need to make it "installable", I had to add some stuff to have the
binaries and header installed automatically when referenced.
The latter reason led me to experiment with ExternalProject.
