Hi. I am working on stm32f072c8t6 mcu using cubemx and want to develop a touch sensing application. I created a project using CubeMX for this. I would like to include the project library "STM32_TouchSensing_Library", but I encounter many errors. What could be the solution to this problem?

>>What could be the solution to this problem?

Add the file(s) containing these functions into your project, either as the source files, or as a library.

@Community member​ I added all the necessary libraries, files, file paths, etc. But I'm getting the same error.

Evidently the linker disagrees.

Including .H files just defines the interface, it does not provide the body code for the functions. The linker can't get closure because there is nothing to bind too.

Grep or Find-in-Files within your system the "TSL_tkey_Init" function, and others if the reside in different files

I just want to improve my own touch sensing application with the shared applications and libraries shared on this link( https://www.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32cube-mcu-packages/stm32cubef0.html#getsoftware-scroll ). I include the libraries in the project as described in this documentation. But it's failing. give an error.
