Build on Windows with MinGW without WSL

[micropicostack]

I tired to build the tool on Windows but the options documented in README.md did not work for me.

I do not have a Visual Studio installation, so I wanted to use MinGW. After some time tinkering around I found that modifying the FindLIBUSB.cmake file and replacing the HINTS $ENV{LIBUSB_ROOT}/VS2019/MS32/static line with HINTS $ENV{LIBUSB_ROOT}/MinGW64/static and running cmake -G "MinGW Makefiles" .. followed by mingw-make forked like a charm, I got my exe.

Now to the question or idea - could we update the FindLIBUSB.cmake to consider 32bit and 64bit machines, Windows MSVC and MinGW lib inclusion based on generator input?

For example something like this ?

if(CMAKE_GENERATOR MATCHES "MinGW")
    HINTS $ENV{LIBUSB_ROOT}/MinGW64/static
else
    HINTS $ENV{LIBUSB_ROOT}/VS2019/MS64/static
endif()

Yes, we've done something similar before :slightly_smiling_face: https://github.com/raspberrypi/picotool/commit/757f2aee3c2c988b4d0c9c15907e243350381d0a

PRs welcome!

If you're just looking to compile picotool on Windows without the overhead of Visual Studio or WSL, MSYS2 works fine with no changes, like we've done for pico-setup-windows.

Okey, I might do a PR then, but I am not that familiar with Cmake. But to make the process as automatic as possible we have to

• Determine if we are running MinGW/Cygwin or Visual Studio generator
• Determine if we are on a 32bit or a 64bit machine

As for Visual Studio folder I guess it will be fixed to 2019 (although it seems there are newer versions - 2022).

Does that sound like a plan?

I got it to work with MinGW64 binaries (v13.2.0), I had to let cmake know that I was using MinGW generator and I then I used mingw32-make.exe to build the executable.

I made the issue as we could expand either on the FindLIBUSB.cmake and automate a little more or add more description to README.md
