FindosgText
-----------

Finds the osgText NodeKit from the OpenSceneGraph toolkit.

.. note::

  In most cases, it's recommended to use the :module:`FindOpenSceneGraph` module
  instead and list osgText as a component.  This will automatically handle
  dependencies such as the OpenThreads and core osg libraries:

  .. code-block:: cmake

    find_package(OpenSceneGraph COMPONENTS osgText)

This module is used internally by :module:`FindOpenSceneGraph` to find the
osgText 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 osgText explicitly or bypass automatic
component detection:

.. code-block:: cmake

  find_package(osgText)

OpenSceneGraph and osgText headers are intended to be included in C++ project
source code as:

.. code-block:: c++
  :caption: ``example.cxx``

  #include <osg/PositionAttitudeTransform>
  #include <osgText/Text>
  // ...

When working with the OpenSceneGraph toolkit, other libraries such as OpenGL may
also be required.

Result Variables
^^^^^^^^^^^^^^^^

This module defines the following variables:

``osgText_FOUND``
  Boolean indicating whether the osgText NodeKit of the OpenSceneGraph
  toolkit is found.  For backward compatibility, the ``OSGTEXT_FOUND``
  variable is also set to the same value.

``OSGTEXT_LIBRARIES``
  The libraries needed to link against to use osgText.

``OSGTEXT_LIBRARY``
  A result variable that is set to the same value as the ``OSGTEXT_LIBRARIES``
  variable.

Cache Variables
^^^^^^^^^^^^^^^

The following cache variables may also be set:

``OSGTEXT_INCLUDE_DIR``
  The include directory containing headers needed to use osgText.

``OSGTEXT_LIBRARY_DEBUG``
  The path to the osgText debug library.

Hints
^^^^^

This module accepts the following variables:

``OSGDIR``
  Environment variable that can be set to help locate the OpenSceneGraph
  toolkit, including its osgText 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 osgText 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(osgText)

  if(osgText_FOUND AND NOT TARGET osgText::osgText)
    add_library(osgText::osgText INTERFACE IMPORTED)
    set_target_properties(
      osgText::osgText
      PROPERTIES
        INTERFACE_INCLUDE_DIRECTORIES "${OSGTEXT_INCLUDE_DIR}"
        INTERFACE_LINK_LIBRARIES "${OSGTEXT_LIBRARIES}"
    )
  endif()

  target_link_libraries(example PRIVATE osgText::osgText)
