FindHarfBuzz
--------------
Find HarfBuzz headers and libraries.
Imported Targets
^^^^^^^^^^^^^^^^
``HarfBuzz::HarfBuzz``
The HarfBuzz library, if found.
``HarfBuzz::ICU``
The HarfBuzz ICU library, if found.
Result Variables
^^^^^^^^^^^^^^^^
This will define the following variables in your project:
``HarfBuzz_FOUND``
true if (the requested version of) HarfBuzz is available.
``HarfBuzz_VERSION``
the version of HarfBuzz.
``HarfBuzz_LIBRARIES``
the libraries to link against to use HarfBuzz.
``HarfBuzz_INCLUDE_DIRS``
where to find the HarfBuzz headers.
``HarfBuzz_COMPILE_OPTIONS``
this should be passed to target_compile_options(), if the
target is not used for linking
