FindosgGA

Finds the osgGA library from the OpenSceneGraph toolkit.

Примечание

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

find_package(OpenSceneGraph COMPONENTS osgGA)

This module is used internally by FindOpenSceneGraph to find the osgGA library. It is not intended to be included directly during typical use of the 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:

find_package(osgGA)

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

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

Добавлено в версии 3.3.

Boolean indicating whether the osgGA library of the OpenSceneGraph toolkit was found.

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.

Deprecated Variables

The following variables are provided for backward compatibility:

OSGGA_FOUND

Устарело, начиная с версии 4.2: Use osgGA_FOUND, which has the same value.

Boolean indicating whether the osgGA library of the OpenSceneGraph toolkit was found.

Examples

Finding osgGA explicitly with this module and creating an interface imported target that encapsulates its usage requirements for linking it to a project target:

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)
