I have a QT project created with a .pro file that I need to migrate it to a CMakeLists. This project uses a simple OpenGL animation to show a 3D model of a hand. I already change it to use CMake, but I encounter 2 problems. (The program compiles but it doesn’t run properly)
1. The memory consumption of the program passes from being 20-50 mb using the .pro file, to 1.3 gb using CMake (Maybe some library being loaded completely or something??)
2. The program runs incredibly slow (like 1 frame every 5-10 seconds) in contrast with the speed from using the .pro file (approx. 3 frames per second)
The question is, what I am doing wrong and how can I fix it?
Here is the .pro file

If needed I can give the output when I compile with make VERBOSE=1
