Qt6 GuiPrivate not found error and suggested fix

[BlaineHein]

When building QtAliceVision with Qt6.10.0 cmake gives error message

CMake Error at src/qtAliceVision/CMakeLists.txt:87 (target_link_libraries):
Target "qtAliceVisionPlugin" links to:

Qt6::GuiPrivate

Solution: Insert line

find_package(Qt6 REQUIRED COMPONENTS GuiPrivate)

into src/qtAliceVision/CMakeLists.txt

Solution adapted from

https://forum.qt.io/topic/155256/building-qt6-from-sources-coreprivate/3

changing COMPONENTS from CorePrivate to GuiPrivate

Should have been listed as Qt6.9.0 in my previous comment.
