CubeMX does not allow user defines that are not number or string

Any pin definition can be set in the graphical view of the microcontroller and is included in the main.h when the code is generated. When I do my own libraries, I decide a standard for naming the pins used in my library, a standard that any user that use my library must follow (of course, I include a comment that describe this obligation in my library's header)

As for any other 'parameters', I do defines before including the headers of my libraries (and mentioned in the library documentation). By example, a device that use I2C, in the main.c file I indicate which I2C peripheral the device should use via a #define before include:

#include <main.h>
#define device_x_use_I2C1
#include 'device_x_library_header.h'
�?�?�?�?�?�?

Inside the 'device_x_library_header.h' file I do:

#ifdef device_x_use_I2C1
 //use the I2C1 parameter in your I2C functions
#else
 //use the I2C2 parameter in your I2C functions
#endif�?�?�?�?�?

I use CubeMX for generating the required initialization code but I use my own 'repository of libraries' built upon LL drivers. I find the pin naming mechanism in the CubeMX to be enough in providing user standardized libraries, without adding something inside CubeMX.

What I would like to have in the 'Project settings' window is a possibility to define a relative path to my (user) repository of libraries/headers.

#define LED_PIN  (GPIOB, 10)

But how would you actually use that in your code?
