</span></div></blockquote><div><br></div><div>James,</div><div><br></div><div>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.</div>
<div><br></div><div>E.g.</div><div><br></div><div>add_executable(foo foo.cc ${PROTO_SRCS} ${PROTO_HDRS})</div><div>target_link_libraries(foo ${PROTOBUF_LIBRARIES})</div><div><br></div><div>Hope that solves your problem.</div>
