QT5 KArchive Not Found

[Viking06]

I am trying to use KArchive to zip a file.
I can get the example file to work if I use CMAKE, but QT is unable to find it the .pro file comments say

Show how to use KArchive using qmake

Set $QMAKEPATH to your KArchive install prefix if this is not found.

QT += KArchive
SOURCES += main.cpp

How do I set the $QMAKEPATH

Hi,

@export QMAKEPATH=/path/to/your/karchive@

in your console where you will run cmake
