# Try to find Harfbuzz include and library directories.

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
