James,
PROTO_SRCS & PROTO_HDRS (in the code snippit you list above) are simply
lists of source & header files to generate. You need to use them in a
target in order for CMake to cause them to be generated.
E.g.
add_executable(foo foo.cc ${PROTO_SRCS} ${PROTO_HDRS})
target_link_libraries(foo ${PROTOBUF_LIBRARIES})
Hope that solves your problem.
