-# - Find gperf executable and provides a macro to generate custom build rules
-#
-# The module defines the following variables:
-# GPERF_FOUND - true is gperf executable is found
-# GPERF_EXECUTABLE - the path to the gperf executable
-# GPERF_VERSION - the version of gperf
-# GPERF_LIBRARIES - The gperf libraries
-#
-# The minimum required version of gperf can be specified using the
-# standard syntax, e.g. FIND_PACKAGE(GPERF 2.5.13)
-#
-#
-# If gperf is found on the system, the module provides the macro:
-# GPERF_TARGET(Name GperfInput GperfOutput [COMPILE_FLAGS <string>])
-# which creates a custom command to generate the <GperfOutput> file from
-# the <GperfInput> file. If COMPILE_FLAGS option is specified, the next
-# parameter is added to the gperf command line. Name is an alias used to
-# get details of this custom command. Indeed the macro defines the
-# following variables:
-# GPERF_${Name}_DEFINED - true is the macro ran successfully
-# GPERF_${Name}_OUTPUTS - the source file generated by the custom rule, an
-# alias for GperfOutput
-# GPERF_${Name}_INPUT - the gperf source file, an alias for ${GperfInput}
-#
-# Gperf scanners oftenly use tokens defined by Bison: the code generated
-# by Gperf depends of the header generated by Bison. This module also
-# defines a macro:
-# ADD_GPERF_BISON_DEPENDENCY(GperfTarget BisonTarget)
-# which adds the required dependency between a scanner and a parser
-# where <GperfTarget> and <BisonTarget> are the first parameters of
-# respectively GPERF_TARGET and BISON_TARGET macros.
