 #.rst:
 # FindGperf
 # -----------
 #
 # Try to find GNU gperf.
 #
 # If the gperf executable is not in your PATH, you can provide
 # an alternative name or full path location with the ``Gperf_EXECUTABLE``
 # variable.
 #
 # This will define the following variables:
 #
 # ``Gperf_FOUND``
 #     True if gperf is available.
 #
 # ``Gperf_EXECUTABLE``
 #     The gperf executable.
 #
 # If ``Gperf_FOUND`` is TRUE, it will also define the following imported
 # target:
 #
 # ``GPerf::Gperf``
 #     The gperf executable.
 #
 # and the following public function:
 #
 #   ecm_gperf_generate(<GperfInput> <OutputFile> <OutputVariable>
 #                      [GENERATION_FLAGS <flags>])
 #
 # Run ``gperf`` on ``<GperfInput>`` to generate ``<OutputFile>``, adding it to
 # the ``<OutputVariable>`` variable which contains the source for the target
 # where ``<OutputFile>`` is going to be built.  The optional
 # ``GENERATION_FLAGS`` argument is needed to pass extra parameters to
 # ``gperf`` (note you cannot override that way the output file).
 #
 # A simple invocation would be:
 #
 # .. code-block:: cmake
 #
 #   ecm_gperf_generate(simple.gperf ${CMAKE_CURRENT_BINARY_DIR}/simple.h MySources)
 #
 # Since 5.35.0.
