# IMPORTANT: in order to get a working build you should use x86_64 MinGW with make, cmake, gcc.
# 100% working MinGW is https://github.com/brechtsanders/winlibs_mingw/releases/download/13.1.0-16.0.5-11.0.0-ucrt-r5/winlibs-x86_64-posix-seh-gcc-13.1.0-mingw-w64ucrt-11.0.0-r5.zip
# Many other distributions I tested don't work in some cases or don't have required tools.
# Also, standalone Cmake installed globally via .msi package does not produce working library, you should use MinGW's Cmake.
# Example of export:
# export PATH=/c/MinGW/bin:/c/ghcup/bin:/c/Program\ Files/Amazon\ Corretto/jdk17.0.9_8/bin/:$PATH
# If you use Msys2, use UCRT64 (NOT Mingw64, because it will crash on launch because of non-posix threads), install these packages:
# pacman -S perl make mingw-w64-ucrt-x86_64-cmake mingw-w64-ucrt-x86_64-gcc
# and export path to ghcup/bin and java
