Run msys2_shell.bat in the C:\msys64 and you will see a BASH window opened. In the BASH prompt, use the following commands to install the necessary packages:

pacman -S base-devel mingw-w64-x86_64-toolchain \
mingw-w64-x86_64-xpm-nox mingw-w64-x86_64-libtiff \
mingw-w64-x86_64-giflib mingw-w64-x86_64-libpng \
