| # Tries to find Flatbuffers headers and libraries. |

| # Usage of this module as follows: |
| # |
| # find_package(Flatbuffers) |
| # |
| # Variables used by this module, they can change the default behaviour and need |
| # to be set before calling find_package: |
| # |
| # Flatbuffers_HOME - |
| # When set, this path is inspected instead of standard library locations as |
| # the root of the Flatbuffers installation. The environment variable |
| # FLATBUFFERS_HOME overrides this veriable. |
| # |
| # This module defines |
| # FLATBUFFERS_INCLUDE_DIR, directory containing headers |
| # FLATBUFFERS_LIBS, directory containing flatbuffers libraries |
| # FLATBUFFERS_STATIC_LIB, path to libflatbuffers.a |
| # FLATBUFFERS_FOUND, whether flatbuffers has been found |
