Raspberry Pi Pico - setting up for C on Windows, but I can't build my own projects

I'm on Windows 10, and I installed the toolchain by following chapter 8.2 of the getting-started-with-pico.pdf file. I created the test-project by following chapter 7 of the same PDF file.

So when I run these same commands in my pico-examples folder it works completely fine.

The problem is here:

-- The C compiler identification is MSVC 19.28.29336.0

The compiler should be arm_none_eabi_gcc. I have the same problem, but I don't know how to change this yet.

You should have two compilers. One cross compiler for the target and another one for the Windows host. The Windows compiler is needed to compile for example elf2uf2.exe.

I had the same problem. Then, I used cmake -G "MinGW Makefiles" .. instead. It worked for me. But for build I used nmake.

Note: MinGW GCC must be installed in your device
