LWIP recompilation

[MMald.19]

Hello Dear Developers

I don't know what is the procedure, but when a file is added to the project, the compiler no matter if it is Keil, STM32cubeide, or IAR, does a complete rebuild while LWIP is added to the project. What should I do or What I can do to prevent recompilation of LWIP while it doesn't matter anything to that library?

Your help is appreciated in advance.

IDE's do this because the effective include files and linkable objects can change.
