FindQt¶
Deprecated since version 3.14: This module is available only if policy CMP0084
is not set to
NEW
. It supports only Qt3 and Qt4. For Qt5 or later versions see
cmake-qt(7)
.
This module finds an installed version of Qt3 or Qt4. Qt is a cross-platform application development framework for creating graphical user interfaces and applications.
Use this module only if the project can work with both Qt3 and Qt4
versions. If a specific version is required, use FindQt4
or
FindQt3
module directly.
Behavior:
If multiple Qt versions are found, the user must set the preferred major Qt version with the
DESIRED_QT_VERSION
variable.If only one Qt version is found, then the
DESIRED_QT_VERSION
is set automatically.Once the
DESIRED_QT_VERSION
variable is set, the correspondingFindQt3
orFindQt4
module is included.
Result Variables¶
This module sets the following variables:
QT4_INSTALLED
TRUE
if Qt4 is found.QT3_INSTALLED
TRUE
if Qt3 is found.
Hints¶
QT_REQUIRED
If this variable is set to
TRUE
before callingfind_package(Qt)
, CMake will raise an error if neither Qt3 nor Qt4 is found.DESIRED_QT_VERSION
Specifies the Qt major version to use. Can be either
3
,4
, or empty, to search for version automatically.
Examples¶
Finding Qt3 or Qt4 version:
find_package(Qt)
