Breakpoints are not being hit - CLion Full Remote Debug - MakeFile - GDB

Question

It doesn't matter what type of remote debug connection I tried.. Full Remote Host, Remote Debug, Remote GDB Server etc.

Actually remote device starts working when I clicked the debug button. I can run it from my CLion but it never hits to my breakpoints..

I'm not professional on remote debugging , actually it is my second work but this time it is on already working ( readymade ) project on my Raspberry pi Lorawan device ( Debian ) . Device connected to my home network and there is a package forwarder app in it. App listens 1680 port.

Normally it is working on remote device with no problem. I downloaded the app to my computer and built the project successfully in CLion. After I tried lots of things, almost every combination of remote debugging and settings. I understood I'm missing some point and I need help. If you can help me you will save my life

Makefile :

If I add -g to CXXFLAGS in https://github.com/remonbonbon/makefile-example , I can debug the app target just fine.
