I've downloaded both MinGW and Cygwin. I follow install instructions from multiple online tutorials, install successfully, my compiler finds all of the correct type paths, and... when I create a new application using C++ it can't find the directory of any of the header files.
There is a screenshot. I'm at a loss at this point, I've literally followed two online tutorials for each install and re-installed them, done multiple restarts in between, etc.
