| # 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 |
