CMake build error: "Could not find a package configuration file provided by Qt5OpenGL"

[Markieautarkie]

Hello,

During the build process of CMake, I stumbled upon the following error message:

Could not find a package configuration file provided by "Qt5OpenGL" with any of the following names:

Qt5OpenGLConfig.cmake
qt5opengl-config.cmake

I double checked the dependencies, but it seems I got all of those installed. Am I missing other specific packages? It might be worth noting that I am running the latest retropie image on a Pi4 (4.7.1, installed on top of Raspbian-Lite), to which I added the PIXEL desktop environment manually.

Thanks in advance!

I was indeed missing a package:

sudo apt install libqt5opengl5-dev

Rebuilding after installing said package fixed the issue!
