FindosgDB

Finds the osgDB library from the OpenSceneGraph toolkit.

Note

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

find_package(OpenSceneGraph COMPONENTS osgDB)

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

find_package(osgDB)

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

example.cxx
#include <osg/PositionAttitudeTransform>
#include <osgDB/DatabasePager>
// ...

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

Result Variables

This module defines the following variables:

osgDB_FOUND

Added in version 3.3.

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

OSGDB_LIBRARIES

The libraries needed to link against to use osgDB.

OSGDB_LIBRARY

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

Cache Variables

The following cache variables may also be set:

OSGDB_INCLUDE_DIR

The include directory containing headers needed to use osgDB.

OSGDB_LIBRARY_DEBUG

The path to the osgDB debug library.

Hints

This module accepts the following variables:

OSGDIR

Environment variable that can be set to help locate the OpenSceneGraph toolkit, including its osgDB 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:

OSGDB_FOUND

Deprecated since version 4.2: Use osgDB_FOUND, which has the same value.

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

Examples

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

find_package(osgDB)

if(osgDB_FOUND AND NOT TARGET osgDB::osgDB)
  add_library(osgDB::osgDB INTERFACE IMPORTED)
  set_target_properties(
    osgDB::osgDB
    PROPERTIES
      INTERFACE_INCLUDE_DIRECTORIES "${OSGDB_INCLUDE_DIR}"
      INTERFACE_LINK_LIBRARIES "${OSGDB_LIBRARIES}"
  )
endif()

target_link_libraries(example PRIVATE osgDB::osgDB)
