Windows build documentation

[colings]

I'm a Windows user and thought it would be nice to have Windows developer documentation, like the Ubuntu one. I spun up a VM so I could make sure I documented all the necessary steps.

• Install MSYS2 and accept defaults
  • When the install finishes, in the console that opens type:
    pacman -Syu
  • Reopen the console if it closes (MSYS2 MSYS), and continue to run the command until there are no more updates.
  • Install the ART dependencies:
    pacman -S mingw-w64-x86_64-gcc mingw-w64-x86_64-gdb mingw-w64-x86_64-make mingw-w64-x86_64-pkg-config mingw-w64-x86_64-cmake mingw-w64-x86_64-ninja mingw-w64-x86_64-gtkmm3 mingw-w64-x86_64-lcms2 mingw-w64-x86_64-fftw mingw-w64-x86_64-exiv2 mingw-w64-x86_64-lensfun mingw-w64-x86_64-libiptcdata mingw-w64-x86_64-gtk3 mingw-w64-x86_64-mimalloc mingw-w64-x86_64-opencolorio mingw-w64-x86_64-libraw
• Install cmake
• Install Visual Studio Code
  • Open Visual Studio
  • Open the extensions marketplace (Ctrl+Shift+X) and install C/C++ Extension Pack
  • Choose File, Open Folder..., and choose the root ART folder
  • Choose to trust the authors
  • You should get a popup saying "Compiler kits may be present in these directories", with a list of directories from your MSYS2 installation. Choose the Yes option to set up the compiler kits. If the popup goes away you can open the command palette (Ctrl+Shift+P) and choose CMake: Scan for Kits to open it again.
  • Open the command palette (Ctrl+Shift+P) and choose CMake: Set Launch/Debug Target. First you'll be prompted to select a kit. Choose CC xx.x.x x86_64-w64-mingw32 (mingw64), where xx.x.x is the version number of the compiler you have installed. Wait until VS is done configuring the project, then you will be prompted to choose a launch target. Choose art (Install).
  • By default the debug configuration will be selected. If you'd like to build a different one, open the command palette and choose CMake: Select Variant.
  • In Visual Studio press Shift+F5 to start debugging.

Hi,
Thanks for the contribution! FYI some information about the building steps can be extracted from the GitHub actions, e.g. windows.yml for windows.

Well that's cool, that would have been handy to find earlier, lol. I should have figured there was a recipe for getting everything set up. Well, this should be useful for anyone else who hasn't ever used cmake with Visual Studio, it was a learning experience for me.
