QtVersionOption¶
Adds a build option to select the major Qt version if necessary,
that is, if the major Qt version has not yet been determined otherwise
(e.g. by a corresponding find_package()
call).
This module is typically included by other modules requiring knowledge
about the major Qt version.
QT_MAJOR_VERSION
is defined to either be “5” or “6”.
Since 5.82.0.
