Thanks to kossebau for pointing that out.

CMake 3.14 ships a module with compatible variables.

This is a slightly modernized version of Pino's original implementation
found in KF5 and Plasma.

We have identical copies of this in kinit, kwin, ksysguard and
powerdevil. This makes it a natural candidate for inclusion in ECM.

It is based on the one that can be found in KWin.

Several KDE projects already use libepoxy (KWin and KDeclarative).

An intended use case is to generate client-side and server-side code for
protocols shipped in the wayland-protocols package with qtwaylandscanner.

Png2Ico provides lower quality icons compared to icoutils as png2ico
predates the current icon standard.
Still lloking for png2ico prints
 * Png2Ico, Executable that converts a collection of PNG files into a Windows icon file, <https://www.winterdrache.de/freeware/png2ico/ or https://commits.kde.org/kdewin>

which confuses new users.

Based on https://phabricator.kde.org/D21695

Several KDE projects use taglib, so we really need to provide a proper
find module in ECM.

AFAIK taglib-config should not be portable, so we don't try to
run it on WIN32. See also:
