FindosgShadow

Finds the osgShadow NodeKit from the OpenSceneGraph toolkit.

Note

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

find_package(OpenSceneGraph COMPONENTS osgShadow)

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

find_package(osgShadow)

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

example.cxx
#include <osg/PositionAttitudeTransform>
#include <osgShadow/ShadowTexture>
// ...

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

Result Variables

This module defines the following variables:

osgShadow_FOUND

Boolean indicating whether the osgShadow NodeKit of the OpenSceneGraph toolkit is found. For backward compatibility, the OSGSHADOW_FOUND variable is also set to the same value.

OSGSHADOW_LIBRARIES

The libraries needed to link against to use osgShadow.

OSGSHADOW_LIBRARY

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

Cache Variables

The following cache variables may also be set:

OSGSHADOW_INCLUDE_DIR

The include directory containing headers needed to use osgShadow.

OSGSHADOW_LIBRARY_DEBUG

The path to the osgShadow debug library.

Hints

This module accepts the following variables:

OSGDIR

Environment variable that can be set to help locate the OpenSceneGraph toolkit, including its osgShadow 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 osgShadow explicitly with this module and creating an interface imported target that encapsulates its usage requirements for linking it to a project target:

find_package(osgShadow)

if(osgShadow_FOUND AND NOT TARGET osgShadow::osgShadow)
  add_library(osgShadow::osgShadow INTERFACE IMPORTED)
  set_target_properties(
    osgShadow::osgShadow
    PROPERTIES
      INTERFACE_INCLUDE_DIRECTORIES "${OSGSHADOW_INCLUDE_DIR}"
      INTERFACE_LINK_LIBRARIES "${OSGSHADOW_LIBRARIES}"
  )
endif()

target_link_libraries(example PRIVATE osgShadow::osgShadow)
