Question
hi, I have been trying to add header files in a folder to my project and also a folder with subfolders of the source files to the same project on stm32 IDE to no avail. I have tried all the method i know of including adding path variables and importi

the images are the file structures of the folder i would like to add to my project. The files are GNU GSL source files i would like to implement on my mcu project. some how it does not seem to fine the header files. the is how they are added #include <gsl/gsl_sf_bessel.h>. I toggled between "" and <>. Does any one have any ideas on how to solve this please. Thanks
