FindQt
|
|
------
|
|
|
|
Searches for all installed versions of Qt3 or Qt4.
|
|
|
|
This module cannot handle Qt5 or any later versions.
|
|
For those, see :manual:`cmake-qt(7)`.
|
|
|
|
This module exists for the :command:`find_package` command only if
|
|
policy :policy:`CMP0084` is not set to ``NEW``.
|
|
|
|
This module 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.
