Building via qmake
==================
The following commands assume the following environment variables are set:
* `$srcdir`: The directory into which the source has been downloaded and
unpacked.
* `_qtver`: The Qt version being used (eg: `5.5.1`).
* `$pkgdir`: The directory into which installable files are places. This is
`/` for local installations, or can be different directory when preparing a
redistributable package.
Either set them accordingly, or replace them in the below commands as desired.
The following sources should be downloaded and unpacked into `$srcdir`:
* This repository (either `master` or a specific tag).
* The Qt sources: `http://download.qt-project.org/official_releases/qt/${_qtver%.*}/$_qtver/single/qt-everywhere-opensource-src-$_qtver.tar.xz`
* `git clone git+https://chromium.googlesource.com/breakpad/breakpad breakpad`
* `git clone git+https://chromium.googlesource.com/linux-syscall-support breakpad-lss`
* telegramdesktop.desktop (The intention is to include this file inside the
source package at some point):
`https://aur.archlinux.org/cgit/aur.git/plain/telegramdesktop.desktop?h=telegram-desktop`
* tg.protocol: `https://aur.archlinux.org/cgit/aur.git/plain/tg.protocol?h=telegram-desktop`
