Unable to add Custom Library in STM32CUBEIDE (Touchgfx Project)

[ZExpo.1]

I have added a Touch screen library and I am unable to integrate it into Touchgfx Project that is opened inside Stm32IDE -I am getting File not found error

What I have done so far-

Added the file using Properties ->c/c++ general-> path and symbols ->Includes (Added My Custom Folder GT911)

But When I am adding the header under Sampletouch.c I am getting

 

"target/STM32TouchController.cpp:24:10: fatal error: GT911/GT911.h: No such file or directory"
But the file shows up using control + Click on Header file
