# Lagrange - A Beautiful Gemini Client
# Copyright: 2020 Jaakko Keränen <jaakko.keranen@iki.fi>
#
# Notes:
# - Required dependencies: SDL 2, OpenSSL 1.1.1, libpcre,
#   GNU libunistring, zlib.
# - the_Foundation is built as a static library from 'lib/the_Foundation',
#   if it exists in that location. The Git repository has it as a submodule.
# - Windows builds require MSYS2. In theory, Clang could be set up on
#   Windows for compiling everything, but the_Foundation still lacks
#   native Win32 implementations for the Socket and Process classes.
# - Windows builds should use the SDL 2 library precompiled for native
#   Windows (MSVC variant) instead of the version from MSYS2 (get it from
#   https://libsdl.org/). To make configuration easier, consider writing
#   for your personal use a pkg-config sdl2.pc file that uses the Windows
#   version of the library.
