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)
