FindosgVolume

Finds the osgVolume NodeKit from the OpenSceneGraph toolkit.

Примечание

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

find_package(OpenSceneGraph COMPONENTS osgVolume)

This module is used internally by FindOpenSceneGraph to find the osgVolume NodeKit. 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 osgVolume explicitly or bypass automatic component detection:

find_package(osgVolume)

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

example.cxx
#include <osg/PositionAttitudeTransform>
#include <osgVolume/Volume>
// ...

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

Result Variables

This module defines the following variables:

osgVolume_FOUND

Добавлено в версии 3.3.

Boolean indicating whether the osgVolume NodeKit of the OpenSceneGraph toolkit was found.

OSGVOLUME_LIBRARIES

The libraries needed to link against to use osgVolume.

OSGVOLUME_LIBRARY

A result variable that is set to the same value as the OSGVOLUME_LIBRARIES variable.

Cache Variables

The following cache variables may also be set:

OSGVOLUME_INCLUDE_DIR

The include directory containing headers needed to use osgVolume.

OSGVOLUME_LIBRARY_DEBUG

The path to the osgVolume debug library.

Hints

This module accepts the following variables:

OSGDIR

Environment variable that can be set to help locate the OpenSceneGraph toolkit, including its osgVolume 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.

Deprecated Variables

The following variables are provided for backward compatibility:

OSGVOLUME_FOUND

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

Boolean indicating whether the osgVolume NodeKit of the OpenSceneGraph toolkit was found.

Examples

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

find_package(osgVolume)

if(osgVolume_FOUND AND NOT TARGET osgVolume::osgVolume)
  add_library(osgVolume::osgVolume INTERFACE IMPORTED)
  set_target_properties(
    osgVolume::osgVolume
    PROPERTIES
      INTERFACE_INCLUDE_DIRECTORIES "${OSGVOLUME_INCLUDE_DIR}"
      INTERFACE_LINK_LIBRARIES "${OSGVOLUME_LIBRARIES}"
  )
endif()

target_link_libraries(example PRIVATE osgVolume::osgVolume)
