Solution: You can't separate template implementations from the header file. Simply don't use a cpp file and put the definition in your header file (.h file).

Why? This is because cpp files can become precompiled sources, while templates are compile-time objects; therefore, the compiler cannot decide what type to use unless specified. So just put all your template undefined implementations in your header .h file.
