Findosg*: Update documentation
- Modules documentation updated and synced.
- Internal comments about headers moved to the modules introduction
  section.
- Added examples sections.
- Used the `<PackageName>_FOUND` variables (CMake 3.3). The uppercased
  `<PACKAGENAME>_FOUND` are also set to the same value.
- Mention of CMake 2.6.3 removed as these version notes are now being
  cleaned in the CMake 4 documentation (CMake docs are at this point
  considering the 2.8.12.2 as the initial state upon which new and
  changed items are documented through versions).
- Added notes that these modules are not intended anymore to be used
  directly except for advanced case scenarios. The FindOpenSceneGraph
  module should be used.
- Fixed osgQt description in FindOpenSceneGraph and synced it a bit.

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