files not being recognized if inside folder

[tmehok]

I will attach my project below if you want the code for reference.

         I am making a HMI for construction workers for reference. Although my screen does everything I've needed thus far it has been hard to organize my code because I keep running into the error of "No such file or directory" when I begin to go from a large file into a more organized file. 

         Due to the nature of my project I do not know if the BSP.h file is generated for everyone. So I will try to be as general as possible. I want to take a function in a file found in Code/Inc/#organizedFileName# I want to include and run this function in a View.cpp file found in, TouchGFX/gui/src/#screenName#. When I leave the file in Code/Inc/#organizedFileName# I get the error "No such file or directory". When I take the file out into Code/Inc I do not get this error. My knowledge tells me it's a compilation path issue but I do not know how to fix that. For now I have been running most variable and function declaration through main.h(THIS IS NOT A GOAL OF MINE). Once I can fix this path issue I want to clean up my code. 

        Any advice and knowledge would be greatly appreciated.

Have you correctly set your Include Paths ?

I think I have set it correctly, I do #include "main.h" for example and that will work. For this specific file I called it #include bsp.h and that gave me an error only when it was in a level deeper than Core/Inc. If it is in Core/Inc/BSP it will not be recognized. I event did the whole path to make sure by doing #include <Core/Inc/BSP/bsp.h>. I attempted to substitute the < for a ", that did not work either. Does this have anything to do with whatever directory is supposed to be higher than Core?

That means you need to add that folder (the one beneath Core/Inc) to your Include Paths.

The easiest way to do that is to right-click the folder in the IDE's Project Explorer, and choose 'Add/remove include path...'

You need to ensure that every folder which contains any header file(s) is included in your Include Paths:

Addendum:

This concept of "Include Paths" is common across (pretty much) all C IDEs - it's not specific to STM32CubeIDE or even Eclipse; eg, see:
