I am trying to convert an old uvProjx to cmake. It is supposed to generate the hex file for a robot. There is no main method, instead there is some custom stuff in the c files, but it should essentially still be compiled like an executable for arm. Compiling works (i think), hoverer right after, the linker throws an error. I have used a converter and ended up with this CMakeLists.txt:

Running make throws this error after compiling:

You can find the c files that are supposed to be compiled here: github link
Doing my research, I found that some people could solve a similar issue by adding
set(CMAKE_SYSTEM_NAME Generic)
I did add this right before project, however, this did not solve the issue. Any ideas and suggestions how to get this running? Again, my goal is to get the hex file of these compiled .c, .h and .cpp files.
Edit: I moved the above to a toolchain file: toolchain.cmake:
include(CMakeForceCompiler)
set(CMAKE_SYSTEM_NAME Generic)
set(CMAKE_SYSTEM_PROCESSOR arm)
set(CMAKE_CROSSCOMPILING 1)
set(CROSS_TARGET_TRIPLET "arm-none-eabi-")
set(CMAKE_C_COMPILER "${CROSS_TARGET_TRIPLET}gcc")
set(CMAKE_ASM_COMPILER "${CROSS_TARGET_TRIPLET}gcc")
set(CMAKE_CXX_COMPILER "${CROSS_TARGET_TRIPLET}g++")
set(CMAKE_TRY_COMPILE_TARGET_TYPE "STATIC_LIBRARY")
I have set to include the argument in VS Code, it does the following:
[main] Configuring project: CMakeTest
[proc] Executing command: "C:\Program Files\CMake\bin\cmake.EXE" --no-warn-unused-cli -DCMAKE_TOOLCHAIN_FILE=C:/Users/Laslo/Development/cpp/hbrs-praktikum/OpenRoboticBoard/UserApp/_Project/CMakeTest/toolchain.make -DCMAKE_EXPORT_COMPILE_COMMANDS:BOOL=TRUE -DCMAKE_BUILD_TYPE:STRING=Debug -DCMAKE_C_COMPILER:FILEPATH=C:\msys64\mingw64\bin\arm-none-eabi-gcc.exe
This still throws the same error when running make. Configure output:

I also found that there is a custom linker in the old project, could that be of use? (Dumb question, of course there is a purpuse, I just have no Idea whats going on so...). You can find the linker in the github repo branch Edit 2: I deleted the build folder to get the output, then it complained it couldn't find the toolchain, turns out I spelled it wrong. Now I get a different error!
