| # FindHg |
| # ------ |
| # |
| # Extract information from a mercurial working copy. |
| # |
| # The module defines the following variables: |
| # |
| # :: |
| # |
| # HG_EXECUTABLE - path to mercurial command line client (hg) |
| # HG_FOUND - true if the command line client was found |
| # HG_VERSION_STRING - the version of mercurial found |
| # |
| # If the command line client executable is found the following macro is defined: |
| # |
| # :: |
| # |
| # HG_WC_INFO(<dir> <var-prefix>) |
| # |
| # Hg_WC_INFO extracts information of a mercurial working copy |
| # at a given location. This macro defines the following variables: |
| # |
| # :: |
| # |
| # <var-prefix>_WC_CHANGESET - current changeset |
| # <var-prefix>_WC_REVISION - current revision |
| # |
| # Example usage: |
| # |
| # :: |
| # |
| # find_package(Hg) |
| # if(HG_FOUND) |
| # message("hg found: ${HG_EXECUTABLE}") |
| # HG_WC_INFO(${PROJECT_SOURCE_DIR} Project) |
| # message("Current revision is ${Project_WC_REVISION}") |
| # message("Current changeset is ${Project_WC_CHANGESET}") |
| # endif() |
