Guide

MSYS2:
pacman -S base-devel mingw64/mingw-w64-x86_64-cmake mingw-w64-x86_64-gtk3 mingw-w64-x86_64-gtkmm3 mingw-w64-x86_64-pkg-config
#Optional: pacman -S mingw-w64-x86_64-glade
#In .bashrc
export PATH=/mingw64/bin:$PATH
export PKG_CONFIG_PATH=/mingw64/lib/pkgconfig

Compiler:
Option 1: Use MSYS2 GCC
pacman -S mingw-w64-x86_64-gcc
Option 2: Use MSVS (Compiler Only) from:

3. Set up project. Go to project root, and run:
mkdir build
cd build
cmake ..
#For GCC, use `cmake -G"MSYS Makefiles" ..`
#If cmake complains no package found, try add `-DCMAKE_PREFIX_PATH=/mingw64/lib` to cmake command
4. Add the debug and build task json files to .vscode folder
5. Run build tasks, and/or Debug
