FindSysProfCapture
------------------

Find Sysprof's ``libsysprof-capture`` headers and libraries.

Imported Targets
^^^^^^^^^^^^^^^^

``SysProfCapture::SysProfCapture``
  The ``libsysprof-capture`` library, if found.

Result Variables
^^^^^^^^^^^^^^^^

This will define the following variables in your project:

``SysProfCapture_FOUND``
  true if (the requested version of) ``libsysprof-capture`` is available.
``SysProfCapture_VERSION``
  version of the found ``libsysprof-capture`` library.
``SysProfCapture_LIBRARIES``
  libraries to link to use ``libsysprof-capture``.
``SysProfCapture_INCLUDE_DIRS``
  where to find the ``libsysprof-capture`` headers.
``SysProfCapture_COMPILE_OPTIONS``
  additional compiler options that should be passed with ``target_compile_options()``
  to targets that use ``libsysprof-capture``, if the imported target is not used
  for linking.
