Converting a C++ Project to C++ Game Template


im trying to convert my c++ project as an own template for later projects.
I found the template directory and placed my project there and added the customized template config file but im not able to compile new projects based on the template project i made.
the template project compiles without problems.

the error message tells that there are some ressources or files duplicated

my question are:

  1. which folders do i need to delete before copying as a template project
  2. are there any tutorials or detailed info based on this topic?

thanks for any help!
