FindBRUNSLI
--------

Find the BRUNSLI libraries

Brunsli encode and decode libraries are built with CMake.
Unfortunately Brunsli does not export cmake config files yet, thus this find module

IMPORTED targets
^^^^^^^^^^^^^^^^

This module defines the following
:prop_tgt:`IMPORTED` target: ``BRUNSLI::ENCODE``
:prop_tgt:`IMPORTED` target: ``BRUNSLI::DECODE``

Result variables
^^^^^^^^^^^^^^^^

This module will set the following variables if found:

``BRUNSLI_INCLUDE_DIR`` - where to find encode.h, decode.h, etc.
``BRUNSLI_ENC_LIB`` - the library to link against to encode Brunsli.
``BRUNSLI_DEC_LIB`` - the library to link against to decode Brunsli.
``BRUNSLI_FOUND`` - TRUE if found
