Provides the following variables:
|
||||
|
||||
* `FFMPEG_INCLUDE_DIRS`: Include directories necessary to use FFMPEG.
|
||||
* `FFMPEG_LIBRARIES`: Libraries necessary to use FFMPEG. Note that this only
|
||||
includes libraries for the components requested.
|
||||
* `FFMPEG_VERSION`: The version of FFMPEG found.
|
||||
|
||||
The following components are supported:
|
||||
|
||||
* `avcodec`
|
||||
* `avdevice`
|
||||
* `avfilter`
|
||||
* `avformat`
|
||||
* `avresample`
|
||||
* `avutil`
|
||||
* `swresample`
|
||||
* `swscale`
|
||||
|
||||
For each component, the following are provided:
|
||||
|
||||
* `FFMPEG_<component>_FOUND`: Libraries for the component.
|
||||
* `FFMPEG_<component>_INCLUDE_DIRS`: Include directories for
|
||||
the component.
|
||||
* `FFMPEG_<component>_LIBRARIES`: Libraries for the component.
|
||||
* `FFMPEG::<component>`: A target to use with `target_link_libraries`.
|
||||
|
||||
Note that only components requested with `COMPONENTS` or `OPTIONAL_COMPONENTS`
|
||||
are guaranteed to set these variables or provide targets.
