# - Searches for all installed versions of QT.
|
||
|
|
# This should only be used if your project can work with multiple
|
||
|
|
# versions of QT. If not, you should just directly use FindQt4 or FindQt3.
|
||
|
|
# If multiple versions of QT are found on the machine, then
|
||
|
|
# The user must set the option DESIRED_QT_VERSION to the version
|
||
|
|
# they want to use. If only one version of qt is found on the machine,
|
||
|
|
# then the DESIRED_QT_VERSION is set to that version and the
|
||
|
|
# matching FindQt3 or FindQt4 module is included.
|
||
|
|
# Once the user sets DESIRED_QT_VERSION, then the FindQt3 or FindQt4 module
|
||
|
|
# is included.
|
||
|
|
#
|
||
|
|
# QT_REQUIRED if this is set to TRUE then if CMake can
|
||
|
|
# not find QT4 or QT3 an error is raised
|
||
|
|
# and a message is sent to the user.
|
||
|
|
#
|
||
|
|
# DESIRED_QT_VERSION OPTION is created
|
||
|
|
# QT4_INSTALLED is set to TRUE if qt4 is found.
|
||
|
|
# QT3_INSTALLED is set to TRUE if qt3 is found.
