Ensure that all unit tests pass

[arrieta]

There are several unit tests that do not currently pass and we cannot continue development until they do.

Errors while running CTest

[fayalalebrun]

@arrieta As of now, all tests pass on my machine running linux (With the exception of the geometry failing test). Are the tests still failing on the latest commit of the master branch? What operating system are you using? I have access and could set up the program to test on both MacOS and Windows if needed.

[fayalalebrun]

#40 fixes the failing tests on MacOS. However, when testing manually, I couldn't get a window to display. However, this is most likely because the version of glfw on my machine most likely had a bug which caused this in Mojave, as reported here: (glfw/glfw#1393)
