FindosgPresentation
-------------------
Finds the osgPresentation NodeKit from the OpenSceneGraph toolkit, available
since OpenSceneGraph version 3.0.0.
.. note::
In most cases, it's recommended to use the :module:`FindOpenSceneGraph` module
instead and list osgPresentation as a component. This will automatically
handle dependencies such as the OpenThreads and core osg libraries:
.. code-block:: cmake
find_package(OpenSceneGraph COMPONENTS osgPresentation)
This module is used internally by :module:`FindOpenSceneGraph` to find the
osgPresentation NodeKit. It is not intended to be included directly during
typical use of the :command:`find_package` command. However, it is available as
a standalone module for advanced use cases where finer control over detection is
needed. For example, to find the osgPresentation explicitly or bypass automatic
component detection:
.. code-block:: cmake
find_package(osgPresentation)
OpenSceneGraph and osgPresentation headers are intended to be included in C++
project source code as:
.. code-block:: c++
:caption: ``example.cxx``
#include <osg/PositionAttitudeTransform>
#include <osgPresentation/SlideEventHandler>
// ...
When working with the OpenSceneGraph toolkit, other libraries such as OpenGL may
also be required.
Result Variables
^^^^^^^^^^^^^^^^
This module defines the following variables:
``osgPresentation_FOUND``
Boolean indicating whether the osgPresentation NodeKit of the
OpenSceneGraph toolkit is found. For backward compatibility, the
``OSGPRESENTATION_FOUND`` variable is also set to the same value.
``OSGPRESENTATION_LIBRARIES``
The libraries needed to link against to use osgPresentation.
``OSGPRESENTATION_LIBRARY``
A result variable that is set to the same value as the
``OSGPRESENTATION_LIBRARIES`` variable.
Cache Variables
^^^^^^^^^^^^^^^
The following cache variables may also be set:
``OSGPRESENTATION_INCLUDE_DIR``
The include directory containing headers needed to use osgPresentation.
``OSGPRESENTATION_LIBRARY_DEBUG``
The path to the osgPresentation debug library.
Hints
^^^^^
This module accepts the following variables:
``OSGDIR``
Environment variable that can be set to help locate the OpenSceneGraph
toolkit, including its osgPresentation NodeKit, when installed in a custom
location. It should point to the OpenSceneGraph installation prefix used when
it was configured, built, and installed: ``./configure --prefix=$OSGDIR``.
Examples
^^^^^^^^
Finding osgPresentation explicitly with this module and creating an interface
:ref:`imported target <Imported Targets>` that encapsulates its usage
requirements for linking it to a project target:
.. code-block:: cmake
find_package(osgPresentation)
if(osgPresentation_FOUND AND NOT TARGET osgPresentation::osgPresentation)
add_library(osgPresentation::osgPresentation INTERFACE IMPORTED)
set_target_properties(
osgPresentation::osgPresentation
PROPERTIES
INTERFACE_INCLUDE_DIRECTORIES "${OSGPRESENTATION_INCLUDE_DIR}"
INTERFACE_LINK_LIBRARIES "${OSGPRESENTATION_LIBRARIES}"
)
endif()
target_link_libraries(example PRIVATE osgPresentation::osgPresentation)
