Additional context

/tmp/wailsbindings is a windows executable, but the build process tries to execute it on the Linux build machine.

I don't like to be the "me too" guy, but it happens for me as well on MacOS.

When executing:

wails build -platform windows/arm64 -o prmonitor_arm64.exe

The output is:

# Building target: windows/arm64

  • Generating bindings:   ERROR   
          
          fork/exec /var/folders/3p/577s80k51c94ym0fp2j2g4xw0000gn/T/wailsbindings: exec format error

          fork/exec /var/folders/3p/577s80k51c94ym0fp2j2g4xw0000gn/T/wailsbindings: exec format error

Also happens if the platform is amd64.

I am compiling on an M3 MacBook Air.
