[CMake] String error Cmake

[Mauricio Klein]

Hello again Andreas!

As i said before, the error was already solved.

In fact, the function header was declared, but the implementation in .cpp
file was not using "Executor::" prefix, so the header declaration hadn't a
proper implementation to the function.

Additionally, i agree that was a mistake of my part: the string type was
found, but no implementation to the function was provided.

Again, thank you very much for your attention!
