FindJPEG
|
|
--------
|
|
|
|
Find the JPEG library (libjpeg)
|
|
|
|
Imported targets
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
This module defines the following :prop_tgt:`IMPORTED` targets:
|
|
|
|
``JPEG::JPEG``
|
|
The JPEG library, if found.
|
|
|
|
Result variables
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
This module will set the following variables in your project:
|
|
|
|
``JPEG_FOUND``
|
|
If false, do not try to use JPEG.
|
|
``JPEG_INCLUDE_DIRS``
|
|
where to find jpeglib.h, etc.
|
|
``JPEG_LIBRARIES``
|
|
the libraries needed to use JPEG.
|
|
``JPEG_VERSION``
|
|
the version of the JPEG library found
|
|
|
|
Cache variables
|
|
^^^^^^^^^^^^^^^
|
|
|
|
The following cache variables may also be set:
|
|
|
|
``JPEG_INCLUDE_DIRS``
|
|
where to find jpeglib.h, etc.
|
|
``JPEG_LIBRARY_RELEASE``
|
|
where to find the JPEG library (optimized).
|
|
``JPEG_LIBRARY_DEBUG``
|
|
where to find the JPEG library (debug).
|
|
|
|
Obsolete variables
|
|
^^^^^^^^^^^^^^^^^^
|
|
|
|
``JPEG_INCLUDE_DIR``
|
|
where to find jpeglib.h, etc. (same as JPEG_INCLUDE_DIRS)
|
|
``JPEG_LIBRARY``
|
|
where to find the JPEG library.
|
