FindosgSim

Finds the osgSim NodeKit from the OpenSceneGraph toolkit.

備註

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

find_package(OpenSceneGraph COMPONENTS osgSim)

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

find_package(osgSim)

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

example.cxx
#include <osg/PositionAttitudeTransform>
#include <osgSim/ImpostorSprite>
// ...

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

結果變數

This module defines the following variables:

osgSim_FOUND

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

OSGSIM_LIBRARIES

The libraries needed to link against to use osgSim.

OSGSIM_LIBRARY

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

快取變數

The following cache variables may also be set:

OSGSIM_INCLUDE_DIR

The include directory containing headers needed to use osgSim.

OSGSIM_LIBRARY_DEBUG

The path to the osgSim debug library.

Hints

This module accepts the following variables:

OSGDIR

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

範例

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

find_package(osgSim)

if(osgSim_FOUND AND NOT TARGET osgSim::osgSim)
  add_library(osgSim::osgSim INTERFACE IMPORTED)
  set_target_properties(
    osgSim::osgSim
    PROPERTIES
      INTERFACE_INCLUDE_DIRECTORIES "${OSGSIM_INCLUDE_DIR}"
      INTERFACE_LINK_LIBRARIES "${OSGSIM_LIBRARIES}"
  )
endif()

target_link_libraries(example PRIVATE osgSim::osgSim)
