FindMPEG

Finds the native MPEG library (libmpeg2).

備註

This module is functionally identical to the FindMPEG2 module, which also finds the libmpeg2 library. Both modules were introduced in the past to provide flexibility in handling potential differences in future versions of the MPEG library and to maintain backward compatibility across CMake releases.

The FindMPEG2 module additionally checks for the SDL dependency and includes it in its usage requirements. For working with libmpeg2, it is recommended to use the FindMPEG2 module instead of this one.

範例

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

find_package(MPEG)

if(MPEG_FOUND AND NOT TARGET MPEG::MPEG)
  add_library(MPEG::MPEG INTERFACE IMPORTED)
  set_target_properties(
    MPEG::MPEG
    PROPERTIES
      INTERFACE_LINK_LIBRARIES "${MPEG_LIBRARIES}"
      INTERFACE_INCLUDE_DIRECTORIES "${MPEG_INCLUDE_DIR}"
  )
endif()
