|
|
---------
|
|
|
|
Find the Libuv library.
|
|
|
|
Imported targets
|

^^^^^^^^^^^^^^^^
|
|
|
|
This module defines the following :prop_tgt:`IMPORTED` targets:
|
|
|
|
``Libuv::Libuv``
|
|
The Libuv library, if found.
|
|
|
|
Result variables
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
This module will set the following variables in your project:
|
|
|
|
``Libuv_FOUND``
|
|
If false, do not try to use Libuv.
|
|
``LIBUV_INCLUDE_DIR``
|
|
where to find libuv headers.
|
|
``LIBUV_LIBRARIES``
|
|
the libraries needed to use Libuv.
|
|
``LIBUV_VERSION``
|
|
the version of the Libuv library found
|
|
|
