Goal:Allow someone that uses the cmake_template to have a single varaible file to add exec, sub dirs, and vscode project default

Allow someone that uses the cmake_template to have a single varaible file to add

• executables
• add sub directories
• set the default vscode project

Thereby not needing to change the cmake files provided by the template. I'm sure there is more to do here but its a start.

Does this change would make it hard to use a project from this template in a fetch_contentable way, because of the new unscoped variable? Maybe not?

the project_variables.cmake file has the same defaults, the goal here was to provide a single .cmake file that allows someone using the template to make change to a single file to name the project appropriately for the user, and set the sub directories for libraries and executables. Otherwise just naming your project something other than "intro" means making several changes to serval files.

Hope that helps!
