* Add possibility to ask for libbenchmark version number (#1004)
Add a header which holds the current major, minor, and
patch number of the library. The header is auto generated
by CMake.
* Do not generate unused functions (#1004)
* Add support for version number in bazel (#1004)
* Fix clang format #1004
* Fix more clang format problems (#1004)
* Use git version feature of cmake to determine current lib version
* Rename version_config header to version
* Bake git version into bazel build
* Use same input config header as in cmake for version.h
* Adapt the releasing.md to include versioning in bazel
* Make generate_export_header.bzl work for Windows.
While I'm here, bring the generated code slightly closer to what CMake
would generate nowadays.
Fixes#1351.
* Fix define.
* Fix export_import_condition.
* Fix guard.
