FindosgManipulator

Finds the osgManipulator NodeKit from the OpenSceneGraph toolkit.

備註

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

find_package(OpenSceneGraph COMPONENTS osgManipulator)

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

find_package(osgManipulator)

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

example.cxx
#include <osg/PositionAttitudeTransform>
#include <osgManipulator/TrackballDragger>
// ...

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

結果變數

該模組定義了以下變數：

osgManipulator_FOUND

在 3.3 版被加入.

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

OSGMANIPULATOR_LIBRARIES

The libraries needed to link against to use osgManipulator.

OSGMANIPULATOR_LIBRARY

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

快取變數

The following cache variables may also be set:

OSGMANIPULATOR_INCLUDE_DIR

The include directory containing headers needed to use osgManipulator.

OSGMANIPULATOR_LIBRARY_DEBUG

The path to the osgManipulator debug library.

提示

This module accepts the following variables:

OSGDIR

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

已棄用的變數

The following variables are provided for backward compatibility:

OSGMANIPULATOR_FOUND

在 4.2 版之後被棄用: Use osgManipulator_FOUND, which has the same value.

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

範例

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

find_package(osgManipulator)

if(osgManipulator_FOUND AND NOT TARGET osgManipulator::osgManipulator)
  add_library(osgManipulator::osgManipulator INTERFACE IMPORTED)
  set_target_properties(
    osgManipulator::osgManipulator
    PROPERTIES
      INTERFACE_INCLUDE_DIRECTORIES "${OSGMANIPULATOR_INCLUDE_DIR}"
      INTERFACE_LINK_LIBRARIES "${OSGMANIPULATOR_LIBRARIES}"
  )
endif()

target_link_libraries(example PRIVATE osgManipulator::osgManipulator)
