Description

When compiling Qt 6.2.0 with MSVC2019, Qt3D (and I'm guessing QtQuick3D) fail to compile due to an internal compiler error occurring at:

\qt3d\src\3rdparty\assimp\src\contrib\pugixml\src\pugixml.hpp(1442)

Code in question:

// Make sure implementation is included in header-only mode
// Use macro expansion in #include to work around QMake (QTBUG-11923)
#if defined(PUGIXML_HEADER_ONLY) && !defined(PUGIXML_SOURCE)
# define PUGIXML_SOURCE "pugixml.cpp"
# include PUGIXML_SOURCE
#endif

Configure command:

// configure.bat -top-level -prefix C:\Engineering\Development\Qt\6.2.0\static\msvc2019_64 -platform win32-msvc -static -debug-and-release -opensource -confirm-license -skip qtwebengine -nomake tools -nomake tests -nomake examples -schannel

While this is ultimately an MSVC issue, there's no telling how long it will take for this bug to be fixed and reporting it is problematic due to the crash possibly relying on the contents of many related files, some of which are clearly customized for the Qt distribution, and not truly being isolated to this section.

I filed this here in the hopes that someone familiar with this modification might have a better idea if this compiler trick modification for QTBUG-11923 is likely to be the culprit, and if so, since that the bug is quite old and centered around qmake, perhaps an alternate solution could now be employed that works around this problem given the change to CMake in Qt6?

Disabling PCH appropriately allows this to be bypassed at the very least.
