// The following part of the code determines the CLIENT_BUILD variable.
// Several mechanisms are used for this:
// * first, if HAVE_BUILD_INFO is defined, include build.h, a file that is
//   generated by the build environment, possibly containing the output
//   of git-describe in a macro called BUILD_DESC
// * secondly, if this is an exported version of the code, GIT_ARCHIVE will
//   be defined (automatically using the export-subst git attribute), and
//   GIT_COMMIT will contain the commit id.
// * then, three options exist for determining CLIENT_BUILD:
//   * if BUILD_DESC is defined, use that literally (output of git-describe)
//   * if not, but GIT_COMMIT is defined, use v[maj].[min].[rev].[build]-g[commit]
//   * otherwise, use v[maj].[min].[rev].[build]-unk
// finally CLIENT_VERSION_SUFFIX is added

// First, include build.h if requested
