|
|
|
|
Finds the LZO library.

|
|
True if the system has the LZO library.
|
|
``LZO_INCLUDE_DIRS``
|
|
Include directories needed to use LZO.
|
|
``LZO_LIBRARIES``
|
|
Libraries needed to link to LZO.
|
|
``LZO_VERSION``
|
|
The version of the LZO library which was found.
|
|
|
|
Cache Variables
|
|
^^^^^^^^^^^^^^^
|
|
|
|
The following cache variables may also be set:
|
|
|
|
``LZO_INCLUDE_DIR``
|
|
The directory containing ``lzo/lzo1x.h``.
|
|
``LZO_LIBRARY``
|
|
The path to the LZO library.
