Float format string flagged as error in editor

[Etienne_Parmentier]

I am using STM32CubeIDE version 1.18.1, and when using float formatting, STM32CubeIDE shows me an error with red squiggles about float formatting not being enabled in my toolchain.

When I go to Project Properties > C/C++ Build > Settings , I see no 'Tool settings' menu, and no linker option to specify. I am using CMake, so I believe this is normal since STM32CubeIDE does not know about my build configuration. How can I make this error disappear while using cmake ?

So some files that STM32CubeIDE uses may not be in the repository.

Start a new project to get those those settings back, copy the c/h files from old project to this new one.
