Did you define Executor::runCommand(...)? --- Aaron Wright

The error is occurring just in this function, but i've assured that string libraries are included.

CMake already does this when you feed it c++ sources. So check you project wether you maybe disabled C++ support, or wether you maybe have C++ code in .c files.
