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 check.h, etc.
``LIBUV_LIBRARIES``
the libraries needed to use Libuv.
``LIBUV_VERSION``
the version of the Libuv library found
