Somehow I could never get to intermediate level in cmake. I read the book, and still clueless. Getting Cuda to run was arbitrary luck. How does one understand (

  I kinda learned CMake on the fly by trying to (and sometimes failing to) use other external C++ libraries. (I’m still not an expert in it though.) Some of the packages had perfect CMake integration (find_package just works), some had to be manually compiled to a library (via add_library), and some used a custom script for installation such that I needed to write a FindXX.cmake file from scratch. You basically learn by haphazardly throwing yourself against the wall multiple times. “Modern” CMake tutorials will help to a certain extent, but the examples they use only use perfectly modern-CMake-ready libraries; real life is often more cruel than that! (especially when you’re doing 3D graphics and need to deal with all sorts of esoteric legacy systems).
