'GLFW3_LIBRARIES' set to 'NOTFOUND'

[creallfluharty]

I am having an issue that very similar to https://github.com/matus-chochlik/oglplus/issues/27

The result of running the configuration:

$ python configure.py --build

I see that the .so files don't seem to match those listed in that thread. How can I resolve this?

HI, cmake is searching for a combination of GLFW/glfw3.h and glfw3.so. While you have the header, you don't seen to have a library with that name, try to create a symlink to libglfw.so.3.2 called glfw3.so in /usr/lib/x86_64-linux-gnu/

HTH

Thank you for your timely response! Unfortunately that didn't seem to resolve the problem :/

Just as an update, I was able to install oglplus by uninstalling GLFW3 and switching to SDL (I also deleted and recloned the repo, which may or may not have been necessary). I'm not sure if that counts as a solution to this problem as a whole, but it does solve mine.
