My latest OpenGL project, where I did all the graphics from scratch, used:
https://www.libsdl.org/ - SDL for window and input
https://github.com/nothings/stb - stb_image to save png files
http://glm.g-truc.net/0.9.7/index.html - glm library for math
http://glew.sourceforge.net/ - glew for loading the OpenGL version
I've had no problems with Windows, Linux, or Mac so far. These things work well, but get out of your way and let you code.
As you learn more, you can replace these libraries with your own code if you really want to understand everything, but it's just too hard to start from scratch when you've never done this before.
