From 84ad104499d9efc0253dae1a60ee070ed375ad95 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Thu, 20 Oct 2022 00:44:55 +0300 Subject: Move test applications to src/apps/ The cam and qcam test application share code, currently through a crude hack that references the cam source files directly from the qcam meson.build file. To prepare for the introduction of hosting that code in a static library, move all applications to src/apps/.
