error in compilation: can't import protobuf header file when protobuf is installed in a different location.

[frankang]

Protobuf is installed under the folder /usr/local/protobuf, I manually set the CMAKE_PREFIX_PATH environment variable in the lightseq/inference/proto/CMakeLists.txt file to include the above installation path. However I still get error during installation (error log pasted below). Could you suggest a way to adapt the code to this new protobuf location? Thanks.

You can try to reinstall protobuf and make sure to set CXXFLAGS:

curl -O -L -C - https://github.com/protocolbuffers/protobuf/releases/download/v3.13.0/protobuf-cpp-3.13.0.tar.gz tar xf protobuf-cpp-3.13.0.tar.gz cd protobuf-3.13.0 && ./autogen.sh ./configure "CFLAGS=-fPIC" "CXXFLAGS=-fPIC" make -j && make install && ldconfig && cd .. && rm -rf protobuf-3.13.0

Thanks，protubuf is installed with "CXXFLAGS=-fPIC" enabled. The above error happens after protobuf is configured to install in a different location.
