Fixed the bug where different source files were referencing a static variable. Turns out static vars are internally linked, which means there was a separate static variable defined for each source. I could have fixed this issue by using extern (see https://stackoverflow.com/questions/10422034/when-to-use-extern-in-c), but instead went with just assigning the shader manually im main. This is becoming very messy and needs a cleanup.
