@xinntao This is no longer "just a bunch of cmake deprecation warnings", but I'm getting actual errors now. In other words: this project fails to build nowadays. Worse yet, it is actually being actively used by various upstream projects, such as https://gitlab.gnome.org/World/Upscaler.

The complete cmake log:

-- Found OpenMP_C: -fopenmp (found version "4.5")
-- Found OpenMP_CXX: -fopenmp (found version "4.5")
-- Found glslangValidator: /usr/bin/glslangValidator
-- Using glslang install located at /usr/lib/cmake
