[bug#60567] [PATCH] gnu: Add ftxui

[Artyom V. Poptsov]

Hello,

this patch adds FXTUI[1], a simple C++ library for terminal based user
interfaces.

0001-gnu-Add-ftxui.patch
Description: Text Data

I decided to place this package in a separate module called "tui.scm" as
there are other libraries for building text-based user interfaces that
can be added in the future (like [2], for example.)

Also to check if the library installed right I tried to build "tiles"
game[3] that is using FXTUI:

--8<---------------cut here---------------start------------->8---
git clone https://github.com/tusharpm/tiles.git
cd tiles
guix shell binutils gcc
mkdir build
cd build
cmake ..
make -j$(nproc)
--8<---------------cut here---------------end--------------->8---

Which worked out flawlessly.

Thanks,
- avp
