#[=======================================================================[.rst:FindVorbis---------- Finds the native vorbis, vorbisenc amd vorbisfile includes and libraries. Imported Targets^^^^^^^^^^^^^^^^ This module provides the following imported targets, if found: ``Vorbis::vorbis``  The Vorbis library``Vorbis::vorbisenc``  The VorbisEnc library``Vorbis::vorbisfile``  The VorbisFile library Result Variables^^^^^^^^^^^^^^^^ This will define the following variables: ``Vorbis_Vorbis_INCLUDE_DIRS``  List of include directories when using vorbis.``Vorbis_Enc_INCLUDE_DIRS``  List of include directories when using vorbisenc.``Vorbis_File_INCLUDE_DIRS``  List of include directories when using vorbisfile.``Vorbis_Vorbis_LIBRARIES``  List of libraries when using vorbis.``Vorbis_Enc_LIBRARIES``  List of libraries when using vorbisenc.``Vorbis_File_LIBRARIES``  List of libraries when using vorbisfile.``Vorbis_FOUND``  True if vorbis and requested components found.``Vorbis_Vorbis_FOUND``  True if vorbis found.``Vorbis_Enc_FOUND``  True if vorbisenc found.``Vorbis_Enc_FOUND``  True if vorbisfile found. Cache variables^^^^^^^^^^^^^^^ The following cache variables may also be set: ``Vorbis_Vorbis_INCLUDE_DIR``  The directory containing ``vorbis/vorbis.h``.``Vorbis_Enc_INCLUDE_DIR``  The directory containing ``vorbis/vorbisenc.h``.``Vorbis_File_INCLUDE_DIR``  The directory containing ``vorbis/vorbisenc.h``.``Vorbis_Vorbis_LIBRARY``  The path to the vorbis library.``Vorbis_Enc_LIBRARY``  The path to the vorbisenc library.``Vorbis_File_LIBRARY``  The path to the vorbisfile library. Hints^^^^^ A user may set ``Vorbis_ROOT`` to a vorbis installation root to tell this module where to look. #]=======================================================================] if(Vorbis_Vorbis_INCLUDE_DIR)  # Already in cache, be silent  set(Vorbis_FIND_QUIETLY TRUE)endif() set(Vorbis_Vorbis_FIND_QUIETLY TRUE)set(Vorbis_Enc_FIND_QUIETLY TRUE)set(Vorbis_File_FIND_QUIETLY TRUE) find_package(Ogg QUIET) find_package(PkgConfig QUIET)pkg_check_modules(PC_Vorbis_Vorbis QUIET vorbis)pkg_check_modules(PC_Vorbis_Enc QUIET vorbisenc)pkg_check_modules(PC_Vorbis_File QUIET vorbisfile) set(Vorbis_VERSION ${PC_Vorbis_Vorbis_VERSION}) find_path(Vorbis_Vorbis_INCLUDE_DIR vorbis/codec.h  HINTS    ${PC_Vorbis_Vorbis_INCLUDEDIR}    ${PC_Vorbis_Vorbis_INCLUDE_DIRS}    ${Vorbis_ROOT}) find_path(Vorbis_Enc_INCLUDE_DIR vorbis/vorbisenc.h  HINTS    ${PC_Vorbis_Enc_INCLUDEDIR}    ${PC_Vorbis_Enc_INCLUDE_DIRS}    ${Vorbis_ROOT}) find_path(Vorbis_File_INCLUDE_DIR vorbis/vorbisfile.h  HINTS    ${PC_Vorbis_File_INCLUDEDIR}    ${PC_Vorbis_File_INCLUDE_DIRS}    ${Vorbis_ROOT}) find_library(Vorbis_Vorbis_LIBRARY  NAMES    vorbis    vorbis_static    libvorbis    libvorbis_static  HINTS    ${PC_Vorbis_Vorbis_LIBDIR}    ${PC_Vorbis_Vorbis_LIBRARY_DIRS}    ${Vorbis_ROOT}) find_library(Vorbis_Enc_LIBRARY  NAMES    vorbisenc    vorbisenc_static    libvorbisenc    libvorbisenc_static  HINTS    ${PC_Vorbis_Enc_LIBDIR}    ${PC_Vorbis_Enc_LIBRARY_DIRS}    ${Vorbis_ROOT}) find_library(Vorbis_File_LIBRARY  NAMES    vorbisfile    vorbisfile_static    libvorbisfile    libvorbisfile_static  HINTS    ${PC_Vorbis_File_LIBDIR}    ${PC_Vorbis_File_LIBRARY_DIRS}    ${Vorbis_ROOT}) include(FindPackageHandleStandardArgs) if(Vorbis_Vorbis_LIBRARY AND Vorbis_Vorbis_INCLUDE_DIR AND Ogg_FOUND)  set(Vorbis_Vorbis_FOUND TRUE)endif() if(Vorbis_Enc_LIBRARY AND Vorbis_Enc_INCLUDE_DIR AND Vorbis_Vorbis_FOUND)  set(Vorbis_Enc_FOUND TRUE)endif() if(Vorbis_Vorbis_FOUND AND Vorbis_File_LIBRARY AND Vorbis_File_INCLUDE_DIR)  set(Vorbis_File_FOUND TRUE)endif() find_package_handle_standard_args(Vorbis  REQUIRED_VARS    Vorbis_Vorbis_LIBRARY    Vorbis_Vorbis_INCLUDE_DIR    Ogg_FOUND  HANDLE_COMPONENTS  VERSION_VAR Vorbis_VERSION)  if(Vorbis_Vorbis_FOUND)  set(Vorbis_Vorbis_INCLUDE_DIRS ${Vorbis_Vorbis_INCLUDE_DIR} ${Ogg_INCLUDE_DIRS})  set(Vorbis_Vorbis_LIBRARIES ${Vorbis_Vorbis_LIBRARY} ${Ogg_LIBRARIES})  if(NOT TARGET Vorbis::vorbis)    add_library(Vorbis::vorbis UNKNOWN IMPORTED)    set_target_properties(Vorbis::vorbis PROPERTIES      INTERFACE_INCLUDE_DIRECTORIES "${Vorbis_Vorbis_INCLUDE_DIR}"      IMPORTED_LOCATION "${Vorbis_Vorbis_LIBRARY}"      INTERFACE_LINK_LIBRARIES Ogg::ogg    )  endif()   if(Vorbis_Enc_FOUND)    set(Vorbis_Enc_INCLUDE_DIRS ${Vorbis_Enc_INCLUDE_DIR} ${Ogg_INCLUDE_DIRS})    set(Vorbis_Enc_LIBRARIES ${Vorbis_Enc_LIBRARY} ${Vorbis_Vorbis_LIBRARIES})    if(NOT TARGET Vorbis::vorbisenc)      add_library(Vorbis::vorbisenc UNKNOWN IMPORTED)      set_target_properties(Vorbis::vorbisenc PROPERTIES        INTERFACE_INCLUDE_DIRECTORIES "${Vorbis_Enc_INCLUDE_DIR}"        IMPORTED_LOCATION "${Vorbis_Enc_LIBRARY}"        INTERFACE_LINK_LIBRARIES Vorbis::vorbis      )    endif()  endif()   if(Vorbis_File_FOUND)    set(Vorbis_File_INCLUDE_DIRS ${Vorbis_File_INCLUDE_DIR} ${Ogg_INCLUDE_DIRS})    set(Vorbis_File_LIBRARIES ${Vorbis_File_LIBRARY} ${Vorbis_Vorbis_LIBRARIES})    if(NOT TARGET Vorbis::vorbisfile)      add_library(Vorbis::vorbisfile UNKNOWN IMPORTED)      set_target_properties(Vorbis::vorbisfile PROPERTIES        INTERFACE_INCLUDE_DIRECTORIES "${Vorbis_File_INCLUDE_DIR}"        IMPORTED_LOCATION "${Vorbis_File_LIBRARY}"        INTERFACE_LINK_LIBRARIES Vorbis::vorbis      )    endif()  endif() endif() mark_as_advanced(Vorbis_Vorbis_INCLUDE_DIR Vorbis_Vorbis_LIBRARY)mark_as_advanced(Vorbis_Enc_INCLUDE_DIR Vorbis_Enc_LIBRARY)mark_as_advanced(Vorbis_File_INCLUDE_DIR Vorbis_File_LIBRARY)
