# Tries to find Google benchmark headers and libraries.
#
# Usage of this module as follows:
#
# find_package(GBenchark)
#
# Variables used by this module, they can change the default behaviour and need
# to be set before calling find_package:
#
# GBenchmark_HOME - When set, this path is inspected instead of standard library
# locations as the root of the benchark installation.
# The environment variable GBENCHMARK_HOME overrides this veriable.
#
# This module defines
# GBENCHMARK_INCLUDE_DIR, directory containing benchmark header directory
# GBENCHMARK_LIBS, directory containing benchmark libraries
# GBENCHMARK_STATIC_LIB, path to libbenchmark.a
# GBENCHMARK_FOUND, whether gbenchmark has been found
