FindLibidn2
-----------
Find the Libidn2 library
Imported targets
^^^^^^^^^^^^^^^^
This module defines the following :prop_tgt:`IMPORTED` targets:
``Libidn2::Libidn2``
The Libidn2 library, if found.
Result variables
^^^^^^^^^^^^^^^^
This module will set the following variables in your project:
``Libidn2_FOUND``
If false, do not try to use Libidn2.
``LIBIDN2_INCLUDE_DIR``
where to find libidn2 headers.
``LIBIDN2_LIBRARIES``
the libraries needed to use Libidn2.
``LIBIDN2_VERSION``
the version of the Libidn2 library found
