# - 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.
#
#  ====================================================================
#  Example:
#
#   find_package(GPERF)
#
#   GPERF_TARGET(MyHash hash.gperf  ${CMAKE_CURRENT_BINARY_DIR}/hash.c)
