Bug#915389: ibus-qt4: Please use pkg-config to detect icu

[Hugh McMaster <hugh.mcmaster@outlook.com>]

Package: ibus-qt4
Version: 1.3.3-3+b1
Severity: normal
Tags: patch

Dear Maintainer,

icu-config has been deprecated by its upstream developers for some years now.
In icu 63.1, icu-config is optional to install, but installed by default. In
the next version, icu-config will no longer be installed by default.

The developers recommend downstream packages use pkg-config to detect the icu
libraries.

I have prepared a patch for cmake to detect the icu libraries using pkg-config.

Thank you
