FindProducer — CMake 4.1.4 Documentation

# FindProducer

Note

Producer (also known as Open Producer) library originated from the osgProducer utility library in early versions of the OpenSceneGraph toolkit and was later developed into a standalone library. The osgProducer was eventually replaced by the osgViewer library, and the standalone Producer library became obsolete and is no longer maintained. For details about OpenSceneGraph usage, refer to the `FindOpenSceneGraph` module.

This module finds the Producer library, a windowing and event handling library designed primarily for real-time graphics applications.

Producer library headers are intended to be included in C++ project source code as:

`example.cxx`

    #include <Producer/CameraGroup>

## Result Variables

This module defines the following variables:

`Producer_FOUND`

  Boolean indicating whether Producer is found. For backward compatibility, the `PRODUCER_FOUND` variable is also set to the same value.

## Cache Variables

The following cache variables may also be set:

`PRODUCER_INCLUDE_DIR`

  The include directory containing headers needed to use Producer.

`PRODUCER_LIBRARY`

  The path to the Producer library needed to link against for usage.

## Hints

This module accepts the following variables:

`PRODUCER_DIR`

  Environment variable that can be set to help locate a custom installation of the Producer library. It should point to the root directory where the Producer library was installed. This should match the installation prefix used when configuring and building Producer, such as with `./configure --prefix=$PRODUCER_DIR`.

Because Producer was historically tightly integrated with OpenSceneGraph, this module also accepts the following environment variables as equivalents to `PRODUCER_DIR` for convenience to specify common installation root for multiple OpenSceneGraph-related libraries at once:

`OSGDIR`

  Environment variable treated the same as `PRODUCER_DIR`.

`OSG_DIR`

  Environment variable treated the same as `PRODUCER_DIR`.

## Examples

Finding the Producer library and creating an imported target that encapsulates its usage requirements for linking to a project target:

    find_package(Producer)

    if(Producer_FOUND AND NOT TARGET Producer::Producer)
      add_library(Producer::Producer INTERFACE IMPORTED)
      set_target_properties(
        Producer::Producer
        PROPERTIES
          INTERFACE_INCLUDE_DIRECTORIES "${PRODUCER_INCLUDE_DIR}"
          INTERFACE_LINK_LIBRARIES "${PRODUCER_LIBRARY}"
      )
    endif()

    target_link_libraries(example PRIVATE Producer::Producer)
