Add CMake build files

[rhgndf]

Allows building with cmake instead, so there is no need to install STM32CubeIDE to build the project. The CMakeLists.txt are generated from creating a STM32 project in STMCube32IDE.

Build commands:

cmake -DCMAKE_TOOLCHAIN_FILE=cubeide-gcc.cmake  -S ./ -B Release -G"Unix Makefiles" -DCMAKE_BUILD_TYPE=Release
make -C Release VERBOSE=1 -j $(nproc)

Replace Release with Debug for debug build.

I have tested compiling on macOS 15.2 & Archlinux
Release works 👍 (flashed file from macOS compile and tested audio input to verify function)
Debug seems broken in linking step (both systems, same error)

• undefined reference to `_sbrk'

Side node to -j will spawn an unlimited amount of jobs which may result in out of memory situations, I recommend -j 8

I don't really use the Debug build, but you're right, it shouldn't be broken.

Thanks for the contribution, will take me some time to look at it

Neither do I so no hurry.

Same error with Release builds, but it was fixed with:

• Removing ${RUNTIME_LIBRARY} from CMAKE_C_FLAGS
• Removing ${RUNTIME_LIBRARY_SYSCALLS} from CMAKE_EXE_LINKER_FLAGS

Fixed!

I don't really work with CMake, but am I right in the assumption, that I need to adjust the CMakeLists.txt everytime I add files to the project in the future?

Does this have any usage in combination with STMCubeIDE or is it just for building without it?

Btw, I think there is a $ missing: https://github.com/skuep/AIOC/pull/101/files#diff-1633612828a396f218b1b411fa1630102f089b6e386fad0823638b988bf7b69dR15

Yes, the CMakeLists.txt needs to be updated, although if you are concerned about this, CMake can automatically add all files matching a pattern like '*.c' to the build if needed.

This is just for building without it. I use it with vscode IDE which I think has a better interface than stm32cubeide since it has features like finding definitions and declaration of functions and structs and integration with git.

Good catch, thanks!
