Windows fixes for CMake & Github CI

[anzz1]

AI for the masses

• Fix CMakeLists.txt to fix building on Windows

• Github CI changes

  • Fixed autobuild for Windows and disabled non-working Mac/Linux builds for now
  • Add feature to manually trigger CI and choose whether to create a new release (workflow_dispatch)
  • Autobuild triggers only on relevant changes (code, not readme) or manually
  • Autorelease triggers only on pushes to master branch or manually

You are missing a C/C++ compiler according to CMake.
You'll need to have one, for example Clang / MinGW (GCC) / MSVC installed and configured with CMake.

nmake is part of Visual Studio (MSVC) toolchain but you either don't have Visual Studio installed or it is not properly configured. Refer to the CMake documentation on how to configure it for Visual Studio. The environment variables need to be set correctly for command line building with vcvars

You can also use the prebuilt binaries for windows
