# 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.
