How to add mutator.cc and mutaotr.h into cmake build files?

[daydayup40]

Hi,

I just want to use the Mutate function in Class protobuf_mutator::Mutator to mutate a protobuf messege in my C project, according to https://github.com/google/libprotobuf-mutator#usage, I should simply include mutator.h and mutator.cc into my build files. I use cmake to generate Makefile. I just add a cmake command "include_directories(/usr/local/include/libprotobuf-mutator" into my CMakelist.txt and add a "#include "/home/my/code/libprotobuf-mutator/src/mutator.h"" into my C source file. After I execute command "cmake .. -DCMAKE_CXX_COMPILER=clang++" and "make", I got many compiler errors like "unknown type name ‘namespace’". My OS is ubuntu 18.04.

I'm very new to a lot of this.There may be a lot of problems. Maybe a example from scratch can solve my problem.

How should I do to use the Mutate function in Class protobuf_mutator::Mutator to mutate a protobuf messege in my C project? How to modify my CMakelist.txt and compiler comand or anything else?

Thanks for your help!

I guess you need to use ExternalProject_Add like
https://github.com/llvm/llvm-project/blob/master/clang/cmake/modules/ProtobufMutator.cmake

and then use like this
