=== Install modified curl package ===
The default curl version shipped with MSYS2 relies on an external certificate bundle for verifying SSL/TLS certificates. While this works fine in the mingw-w64 shell itself, it will break SSL verification outside the mingw-w64 shell. Since our cloud integration features rely on a working SSL implementation, we need to build our own curl release. Thanks to the PKGBUILD already provided by the MSYS2/Mingw-w64 developers, this is pretty straight forward.
First, we need to install a few dependencies. This has to be don in the MSYS2 shell.
pacman -S msys/openssl-devel msys/libmetalink-devel
Next, clone the repository containing the mingw-w64 package files in a seperate directory:
git clone https://github.com/msys2/MINGW-packages
