Not sure why cmake is giving an error because of overloaded functions

[Hugo-Pereira]

I think it's because const char *format and const utility::char_t *format ends up being the same type on Linux, which makes those two functions void appendCode (const utility::char_t *format, ...) ; and void appendCode (const char *format, ...) ; have the same signature.

Haven't managed to find a solution for it yet though

For what its worth I have this bug replicated in a dockerfile: https://github.com/AfterNow/FBX-glTF/tree/feature-docker

To build run docker-compose build. The error is

** The Dockerfile is pretty messy right now, there are some out of order apt-get commands, I didn't want to invalidate the casablanca build after spending an hour compiling.
