Bug 414041

SUMMARY
KwindowSystem fails on yocto due to XFixes Library not found by cmake.

STEPS TO REPRODUCE
1. Setup the Yocto enviroment
$ mkdir openstlinux-4.19-thud-mp1-19-10-09
$ cd openstlinux-4.19-thud-mp1-19-10-09
$ repo init -u https://github.com/STMicroelectronics/oe-manifest.git -b refs/tags/openstlinux-4.19-thud-mp1-19-10-09
$ repo sync
$ DISTRO=openstlinux-weston MACHINE=stm32mp1 source layers/meta-st/scripts/envsetup.sh
2. Get all the layers from the "ADDITIONAL INFORMATION" section
3. Checkout the master branches on all meta-layers as provided in "ADDITIONAL INFORMATION" section
4. Start Yocto Build:
$ bitbake -k core-image-plasma-mobile

OBSERVED RESULT
| CMake Error at src/CMakeLists.txt:40 (message):
|   The XFixes library could not be found.  Please install the development
|   package for it.

EXPECTED RESULT
Kwindowsystem should have found xfixes library and the build would then start.
