For all our developers, and for anyone who compiles our code from source, I have something for you to try. I have created premake 5 build scripts for our source code, which I hope will eventually replace our current project files which all have to be updated when something changes. I have created a pull request with all of the details about the change at https://github.com/BZFlag-Dev/bzflag/pull/62, and the source code can be obtained from the "premake" branch of https://github.com/macsforme/bzflag.git.
Please try it out and let us know of any issues that arise. It will be a big change, so it will help us if people test this extensively.
