问题
I would like to test CLion for my stm32 project since it now support remote debugging! To do so I need to setup Cmake for my project and it is my issue.
I tried using this link which seems to be depreciated so I made some changes. It almost builds but there is a problem with the .elf .bin .hex.

Got it to work, thanks to Chris for the guidance. The issue was the ASM was not build and I had to link arm object copy.
