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
|
