# Establece la política CMP0072 para indicar cómo se debe seleccionar la implementación de OpenGL.
# En este caso, se elige la opción "GLVND", que utiliza bibliotecas modernas y modulares (libOpenGL, libGLX),
# en lugar de la biblioteca OpenGL clásica (libGL). Esto mejora la compatibilidad con drivers recientes
# y evita ambigüedades cuando se encuentran múltiples implementaciones de OpenGL en el sistema.
