Okay, so I got this build tree working. I had to: (1) Modify FindProtobuf.cmake (the build rule) so that I can specify the proto_path (2) Modify each .proto import to specify the file to import using the full path from the root, even if the files are parallel to the .proto source. (3) Add CMAKE_SOURCE_DIR (the source tree root) to the proto_path (4) Add CMAKE_BINARY_DIR (the build root) to the gcc_path. (5) Do a clean build. I had old generated .pb.h files in the source tree, and they were being included rather then the newly generated files that lives in the build-tree.
Thanks for your help.
