QT5-5.15x and PyQT5-5.15x compiling issues

[Ian Wilson]

For the 2021 VFX Platform, has anyone run into issues compiling QT5-5.15X and PyQt5-5.15.X?

We are using `GCC 9.3.1` and `Python 3.7.9` on `CentOS 7.6`

I cannot seem to sort out how to get past `#error "Qt requires C++11 support`

I believe QT still needs C++11 support even though we are targeting C++17.

I see in the source files where this is coming from, but not sure how to work around it.

If I comment out the check, then it still fails with the next error `error: ‘QAtomicOps’ does not name a type typedef QAtomicOps<T> Ops;`

Anyone have these issue and know how to solve it?

I successfully built QT5-5.15.2 using the script https://github.com/AcademySoftwareFoundation/aswf-docker/blob/master/scripts/base/build_qt.sh Both specifically with c++11 and c++17. But when I go to build PyQT 5.15.2 I still get the same error error "Qt requires C++11 support" Does anyone have a script they would be willing to share for compiling PyQT?
