| # This cmake module sets the project version and partial version | ||
| # variables by analysing the git tag and commit history. It expects git | ||
| # tags defined with semantic versioning 2.0.0 (http://semver.org/). | ||
| # | ||
| # The module expects the PROJECT_NAME variable to be set, and recognizes | ||
| # the GIT_FOUND, GIT_EXECUTABLE and VERSION_UPDATE_FROM_GIT variables. | ||
| # If Git is found and VERSION_UPDATE_FROM_GIT is set to boolean TRUE, | ||
| # the project version will be updated using information fetched from the | ||
| # most recent git tag and commit. Otherwise, the module will try to read | ||
| # a VERSION file containing the full and partial versions. The module | ||
| # will update this file each time the project version is updated. | ||
| # | ||
| # Once done, this module will define the following variables: | ||
| # | ||
| # ${PROJECT_NAME}_VERSION_STRING - Version string without metadata | ||
| # such as "v2.0.0" or "v1.2.41-beta.1". This should correspond to the | ||
| # most recent git tag. | ||
| # ${PROJECT_NAME}_VERSION_STRING_FULL - Version string with metadata | ||
| # such as "v2.0.0+3.a23fbc" or "v1.3.1-alpha.2+4.9c4fd1" | ||
| # ${PROJECT_NAME}_VERSION - Same as ${PROJECT_NAME}_VERSION_STRING, | ||
| # without the preceding 'v', e.g. "2.0.0" or "1.2.41-beta.1" | ||
| # ${PROJECT_NAME}_VERSION_FULL - Same as ${PROJECT_NAME}_VERSION_STRING_FULL, | ||
| # such as "2.0.0+3.a23fbc" or "1.3.1-alpha.2+4.9c4fd1" | ||
| # ${PROJECT_NAME}_VERSION_MAJOR - Major version integer (e.g. 2 in v2.3.1-RC.2+21.ef12c8) | ||
| # ${PROJECT_NAME}_VERSION_MINOR - Minor version integer (e.g. 3 in v2.3.1-RC.2+21.ef12c8) | ||
| # ${PROJECT_NAME}_VERSION_PATCH - Patch version integer (e.g. 1 in v2.3.1-RC.2+21.ef12c8) | ||
| # ${PROJECT_NAME}_VERSION_TWEAK - Tweak version string (e.g. "RC.2" in v2.3.1-RC.2+21.ef12c8) | ||
| # ${PROJECT_NAME}_VERSION_AHEAD - How many commits ahead of last tag (e.g. 21 in v2.3.1-RC.2+21.ef12c8) | ||
| # ${PROJECT_NAME}_VERSION_GIT_SHA - The git sha1 of the most recent commit (e.g. the "ef12c8" in v2.3.1-RC.2+21.ef12c8) | ||
