## # vcpkg_from_gitlab
##
## Download and extract a project from Gitlab instances. Enables support for `install --head`.
##
## ## Usage:
## ```cmake
## vcpkg_from_gitlab(
## GITLAB_URL <https://gitlab.com>
## OUT_SOURCE_PATH <SOURCE_PATH>
## REPO <gitlab-org/gitlab-ce>
## [REF <v10.7.3>]
## [SHA512 <45d0d7f8cc350...>]
## [HEAD_REF <master>]
## [PATCHES <patch1.patch> <patch2.patch>...]
## )
## ```
##
## ## Parameters:
##
## ### GITLAB_URL
## The URL of the Gitlab instance to use.
##
## ### OUT_SOURCE_PATH
## Specifies the out-variable that will contain the extracted location.
##
## This should be set to `SOURCE_PATH` by convention.
##
## ### REPO
## The organization or user plus the repository name on the Gitlab instance.
##
## ### REF
## A stable git commit-ish (ideally a tag) that will not change contents. **This should not be a branch.**
##
## For repositories without official releases, this can be set to the full commit id of the current latest master.
##
## If `REF` is specified, `SHA512` must also be specified.
##
## ### SHA512
## The SHA512 hash that should match the archive (${GITLAB_URL}/${REPO}/-/archive/${REF}/${REPO_NAME}-${REF}.tar.gz).
## The REPO_NAME variable is parsed from the value of REPO.
##
## This is most easily determined by first setting it to `1`, then trying to build the port. The error message will contain the full hash, which can be copied back into the portfile.
##
## ### HEAD_REF
## The unstable git commit-ish (ideally a branch) to pull for `--head` builds.
##
## For most projects, this should be `master`. The chosen branch should be one that is expected to be always buildable on all supported platforms.
##
## ### PATCHES
## A list of patches to be applied to the extracted sources.
##
## Relative paths are based on the port directory.
##
## ## Notes:
## At least one of `REF` and `HEAD_REF` must be specified, however it is preferable for both to be present.
##
## This exports the `VCPKG_HEAD_VERSION` variable during head builds.
##
## ## Examples:
## * [curl][https://github.com/Microsoft/vcpkg/blob/master/ports/curl/portfile.cmake#L75]
## * [folly](https://github.com/Microsoft/vcpkg/blob/master/ports/folly/portfile.cmake#L15)
## * [z3](https://github.com/Microsoft/vcpkg/blob/master/ports/z3/portfile.cmake#L13)
