Final Report doesn't distinguish system settings
Added ability to have 'sections' to group stuff
Added value function to display options as ON / OFF / value / -undefined-
Added sections System, Config, Libraries
Added a bunch of data to System and Config. Moved some out of Libraries as appropriate.
Removes the BUILD_QT5 flag and adds a new FREECAD_QT_VERSION option,
which can be set to either "Auto" (default), 5, or 6. Auto detects which
version of Qt is installed on the system and chooses it. If both version
are installed, Qt5 is used.
Note that this DOES NOT implement compiling against Qt6, it only adds
the necessary cMake infrastructure to begin work on the source code
changes that will be required.
Commit 024bde641c ("Update FindPySide2Tools.cmake") removed the
versioned names of uic/rcc, which are at least used on openSUSE
and Fedora.
Instead of determining the path of uic/rcc manually, just use
the imported executable targets. rcc comes from QtCore, while
uic comes from QtWidgets.
Fixes#6445.
Found that on ubuntu 20.04 where QT is still at 5.12, these are called pyuic5 and pyrcc5 now and cmake will not find these and then the build fails without this change
Since PySide2 5.14, 'pyside2-rcc' and 'pyside2-uic' have been renamed into plain 'rcc' and 'uic'.
This leads FindPySide2Tools.cmake to no longer find rcc/uic, as reported in bug #4229 (https://www.freecadweb.org/tracker/view.php?id=4229) and prevents compilation.
FindPySide2Tools has been updated accordingly.
Non GNU sed on macOS expects suffix after -i option (can be empty str).
However, removing the comments from the pyside generated files is not a necessary
operation (presumably done to avoid a diff when no code changed), so simply skip the operation on macOS
