Migrate to the LIEF library.

[EndrII]

The LIEF library has support all needed for the CQtDeployer functionality.

The migrate to the LIEF library should be fix next issues:

1. Support the Mac OS. Support for macOS #166 [WIP] Mac OS support #536
2. Parsing delay loaded libraries on Windows. Can't add some extra libraries to the application #531
3. Strip functionality on Windows.

[EndrII]

This change is important.

In one of my projects(trying to migrate it from 5.11 to 5.15) I have an issue with an app installed using the installer. Think it happens because some of the Qt dependencies are not detected properly.
App can't start because xcb plugin can't be loaded.
And there is no more information, sadly(

OS: Astra Linux Common Edition

PS: When I build and start application using IDE it starts and works perfectly

Hm, show me please your tree of a distributionkit folder.
and show a depends list of the libqxcb.so of your project.

tree DistributionKit

ldd DistributionKit/plugins/platforms/libqxcb.so

I think that the problem is that the system does not have enough libraries for the correct operation of the xcb plugin

Ok, I’ll provide more information later. But the fact is that application starts and work using IDE.
