Qt 6.7.2 - Could NOT find OpenGL
-
Hi,
I recently installed Qt 6.7.2 via the maintenance tool on a linux system (Opensuse Tumbleweed).
While opening an older project from another machine I set CMAKE_PREFIX_PATH to the new location of the Qt installation and get now the following messages:
[cmake] Führe /usr/bin/cmake -S /home/joachim/nas/08_source/07_C++/JHXManager -B /home/joachim/nas/08_source/07_C++/JHXManager/build/Desktop_Qt_6_7_2-Debug in /home/joachim/nas/08_source/07_C++/JHXManager/build/Desktop_Qt_6_7_2-Debug aus.

How to fix!

Hi,
Did you install the OpenGL development package ?
-
In the meanwhile I could fix two issues. One typo and a misunderstanding.
OpenGL development package is now installed and everything is running. I was not aware that there are no general OpenGL dev files but special ones for Qt. Since I am not using the packages by my distro provider but from Qt directly I thought the devel files from the Linux distribution are not needed.
Thnx

There are no "special ones for Qt". The OpenGL dev package is required as it's your distribution that handle this low level dependency.

From the looks of it that package is the Qt opengl module development files which is not the same as the OpenGL librairies that were missing. That package may have the latter as dependency though.
