Ninja check failing

[xansec]

After running the cmake commands here, I get:

$ ninja check

[..output...]

I had the same issue and fixed it by adding this flag to the cmake command:

-DLIB_PROTO_MUTATOR_DOWNLOAD_PROTOBUF=ON

So:

cmake .. -GNinja -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_BUILD_TYPE=Debug -DLIB_PROTO_MUTATOR_DOWNLOAD_PROTOBUF=ON

Thanks! That's a lot better than my solution of

sed -i 's/descriptor_->requires_utf8_validation()/true/' /src/libprotobuf-mutator/src/field_instance.h

(but this should probably still be resolved upstream.)
