My first ever course on Udemy is out now and it is on the topic of CMake:
I have quite some years of professional programming experience and for a few years I’ve extensively worked with CMake. I also have a blog with some free articles on topics regarding CMake that you might find useful - https://thatonegamedev.com
I hope you like it and if you do take it please leave a review. It would be really helpful for me as a new instructor.
