* Compile rlgl module using:
* gcc -c rlgl.c -Wall -std=c99 -DRLGL_STANDALONE -DRAYMATH_IMPLEMENTATION -DGRAPHICS_API_OPENGL_33
*
+* NOTE: rlgl module requires the following header-only files:
+* external/glad.h - OpenGL extensions loader (stripped to only required extensions)
+* shader_standard.h - Standard shader for materials and lighting
+* shader_distortion.h - Distortion shader for VR
+* raymath.h - Vector and matrix math functions
+*
* Compile example using:
-* gcc -o $(NAME_PART).exe $(FILE_NAME) rlgl.o -lglfw3 -lopengl32 -lgdi32 -std=c99
+* gcc -o rlgl_standalone.exe rlgl_standalone.c rlgl.o -lglfw3 -lopengl32 -lgdi32 -std=c99
