## # vcpkg_from_bitbucket
##
## Download and extract a project from Bitbucket.
## Enables support for installing HEAD `vcpkg.exe install --head <port>`.
##
## ## Usage:
## ```cmake
## vcpkg_from_bitbucket(
## OUT_SOURCE_PATH <SOURCE_PATH>
## REPO <Microsoft/cpprestsdk>
## [REF <v2.0.0>]
## [SHA512 <45d0d7f8cc350...>]
## [HEAD_REF <master>]
## [PATCHES <patch1.patch> <patch2.patch>...]
## )
## ```
##
## ## Parameters:
## ### 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 and repository on GitHub.
##
## ### 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 (https://bitbucket.com/${REPO}/get/${REF}.tar.gz).
##
## 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:
##
## * [blaze](https://github.com/Microsoft/vcpkg/blob/master/ports/blaze/portfile.cmake)
