What is telega?.

According to the Github repository:

Telega: telega.el is full featured unofficial client for Telegram platform for GNU Emacs.

As you may know, my main OS, at this time (2024-08-21) is NixOS, so I was trying to install Telega in my emacs, but as you can imagine, the file system hierarchy don’t works “normal” in NixOS, so is a little tricky set up the environment to actually make Telega works.

Requisites:

gnumake. (To compile).
cmake (To compile).
tdlib (Version > 1.8.29).

Process of installation.

install the dependencies using your configuration.nix, home-manager, or wathever method you use to install packages in NixOS.
Install Telega in emacs.
```
1(use-package telega
2:ensure t)
```
Now, because I use NixOS (by the way), you must know that the file system hierarchy don’t works same as in linux or macOS, so I need to declare where telega is going to see the tdlib libraries, so:
```
1(setq telega-server-lib-prefix "/home/user/.nix-profile/")
```
Compile Telega-server inside emacs.
```
1M-x telega-server-build
```
Or simply run telega:
```
1M-x telega
```

With that, Telega must be compiled, and ready to go.
