Hi!

Thanks for report! Verified.

To verify on Linux, download from github, and install locally:

https://github.com/protocolbuffers/protobuf/releases
tar xvf ~/Download/protobuf-cpp-3.7.0.tar.gz 
./configure --prefix=/tmp/protobuf37
make -j8
make install
cmake .. -DWITH_PROTOBUF=system -DCMAKE_PREFIX_PATH=/tmp/protobuf37 -DWITH_DEBUG=1

protobuf 3.7.1 might have better compatibility, because https://github.com/protocolbuffers/protobuf/pull/5928

Just tested 3.7.1 (macOS brew build) and indeed it works

Fixed in 8.0.17.

Compilation failure occurred when building with Protobuf 3.7.0.

If this is currently broken but fixed in v8.0.17, where can I download v8.0.17?
