atlas_add_alias(...) Fix, master branch (2020.03.04.)
As it was pointed out in ATLINFR-2524, the atlas_add_alias(...)
function was not implemented quite perfectly.
Instead of just patching the previous implementation, I decided to quite fundamentally re-write how this function would work. As the previous implementation came from a time when I just started to learn about CMake... Now I know better how such a thing should be implemented...
