## # vcpkg_from_gitlab ## ## Download and extract a project from Gitlab instances. Enables support for `install --head`. ## ## ## Usage: ## ```cmake ## vcpkg_from_gitlab( ## GITLAB_URL ## OUT_SOURCE_PATH ## REPO ## [REF ] ## [SHA512 <45d0d7f8cc350...>] ## [HEAD_REF ] ## [PATCHES ...] ## ) ## ``` ## ## ## 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}-${REF}.tar.gz). ## The REPO_NAME variable is parsed from the value of REPO. ## ## This is most easily determined by first setting it to `1`, then trying to build the port. The error message will contain the full hash, which can be copied back into the portfile. ## ## ### HEAD_REF ## The unstable git commit-ish (ideally a branch) to pull for `--head` builds. ## ## For most projects, this should be `master`. The chosen branch should be one that is expected to be always buildable on all supported platforms. ## ## ### PATCHES ## A list of patches to be applied to the extracted sources. ## ## Relative paths are based on the port directory. ## ## ## Notes: ## At least one of `REF` and `HEAD_REF` must be specified, however it is preferable for both to be present. ## ## This exports the `VCPKG_HEAD_VERSION` variable during head builds. ## ## ## Examples: ## * [curl][https://github.com/Microsoft/vcpkg/blob/master/ports/curl/portfile.cmake#L75] ## * [folly](https://github.com/Microsoft/vcpkg/blob/master/ports/folly/portfile.cmake#L15) ## * [z3](https://github.com/Microsoft/vcpkg/blob/master/ports/z3/portfile.cmake#L13) ## function(vcpkg_from_gitlab) set(oneValueArgs OUT_SOURCE_PATH GITLAB_URL USER REPO REF SHA512 HEAD_REF) set(multipleValuesArgs PATCHES) cmake_parse_arguments(_vdud "" "${oneValueArgs}" "${multipleValuesArgs}" ${ARGN}) if(NOT DEFINED _vdud_GITLAB_URL) message(FATAL_ERROR "GITLAB_URL must be specified.") endif() if(NOT DEFINED _vdud_OUT_SOURCE_PATH) message(FATAL_ERROR "OUT_SOURCE_PATH must be specified.") endif() if((DEFINED _vdud_REF AND NOT DEFINED _vdud_SHA512) OR (NOT DEFINED _vdud_REF AND DEFINED _vdud_SHA512)) message(FATAL_ERROR "SHA512 must be specified if REF is specified.") endif() if(NOT DEFINED _vdud_REPO) message(FATAL_ERROR "REPO must be specified.") endif() if(NOT DEFINED _vdud_REF AND NOT DEFINED _vdud_HEAD_REF) message(FATAL_ERROR "At least one of REF and HEAD_REF must be specified.") endif() if(VCPKG_USE_HEAD_VERSION AND NOT DEFINED _vdud_HEAD_REF) message(STATUS "Package does not specify HEAD_REF.
