Having issue building Qt5 on RHEL 8

I am getting this latest release 1.2.1 and from the main branch 1.2.2

We are using the Alma variant of RHEL.
I had no issues building on Alma 9. I'll try a different Alma 8 machine in a bit.

Did you were able to sort out the reason for this behaviour? If Qt5 is installed in a standard location on a linux machine find_package(Qt5 ...) should be able to find it. I haven't had any reports from linux users about issues with this procedure for a very long time, so I suppose it's working correctly. But I have not tested Alma distribution specifically.

I did not get it working. I tried on several machines with the same results (both CentOS Stream 8 and Alma 8). I have the default Qt5 RPMs installed, I am too busy to build lots of packages to keep at leading edge, I like to keep things mainstream.

Alma is another RHEL clone, same as CentOS used be.

Again, no issue with RHEL/Alma 9, Windows 10, or macOS Monterey through Sequoia.

We are 90% moved to RHEL/Alma 9 at this point. Combine that my old Quarter 1.1.0 RPM I built for CentOS 8 some years ago works, so I stopped pursuing the latest updates.

Just in case you are not up on current linux events: Redhat bought CentOS. Created CentOS Stream 8, stuffed it between Fedora and RHEL. Then end of life'd it after ~5 years (and I think moved onto Stream 9). It was nice in principle, but some hiccups, and no LTS. Anyways, after being CentOS folks since CentOS 5, we jumped ship to Alma.
