# FindMPEG2

Finds the native MPEG2 library (libmpeg2).

Note

Depending on how the native libmpeg2 library is built and installed, it may depend on the SDL (Simple DirectMedia Layer) library. If SDL is found, this module includes it in its usage requirements when used.

## Result Variables

This module defines the following variables:

`MPEG2_FOUND`

  Boolean indicating whether the libmpeg2 library is found.

`MPEG2_LIBRARIES`

  Libraries needed to link against to use libmpeg2.

## Cache Variables

The following cache variables may be also set:

`MPEG2_INCLUDE_DIR`

  The directory containing the `mpeg2.h` and related headers needed to use libmpeg2 library.

`MPEG2_mpeg2_LIBRARY`

  The path to the libmpeg2 library.

`MPEG2_vo_LIBRARY`

  The path to the vo (Video Out) library.

## Examples

Finding libmpeg2 library and creating an imported interface target for linking it to a project target:

    find_package(MPEG2)

    if(MPEG2_FOUND AND NOT TARGET MPEG2::MPEG2)
      add_library(MPEG2::MPEG2 INTERFACE IMPORTED)
      set_target_properties(
        MPEG2::MPEG2
        PROPERTIES
          INTERFACE_LINK_LIBRARIES "${MPEG2_LIBRARIES}"
          INTERFACE_INCLUDE_DIRECTORIES "${MPEG2_INCLUDE_DIR}"
      )
    endif()

    target_link_libraries(project_target PRIVATE MPEG2::MPEG2)
