## # vcpkg_download_distfile
|
|
##
|
|
## Download and cache a file needed for this port.
|
|
##
|
|
## This helper should always be used instead of CMake's built-in `file(DOWNLOAD)` command.
|
|
##
|
|
## ## Usage
|
|
## ```cmake
|
|
## vcpkg_download_distfile(
|
|
## <OUT_VARIABLE>
|
|
## URLS <http://mainUrl> <http://mirror1>...
|
|
## FILENAME <output.zip>
|
|
## SHA512 <5981de...>
|
|
## )
|
|
## ```
|
|
## ## Parameters
|
|
## ### OUT_VARIABLE
|
|
## This variable will be set to the full path to the downloaded file. This can then immediately be passed in to [`vcpkg_extract_source_archive`](vcpkg_extract_source_archive.md) for sources.
|
|
##
|
|
## ### URLS
|
|
## A list of URLs to be consulted. They will be tried in order until one of the downloaded files successfully matches the SHA512 given.
|
|
##
|
|
## ### FILENAME
|
|
## The local name for the file. Files are shared between ports, so the file may need to be renamed to make it clearly attributed to this port and avoid conflicts.
|
|
##
|
|
## ### SHA512
|
|
## The expected hash for the file.
|
|
##
|
|
## If this doesn't match the downloaded version, the build will be terminated with a message describing the mismatch.
|
|
##
|
|
## ### SKIP_SHA512
|
|
## Skip SHA512 hash check for file.
|
|
##
|
|
## This switch is only valid when building with the `--head` command line flag.
|
|
##
|
|
## ## Notes
|
|
## The helper [`vcpkg_from_github`](vcpkg_from_github.md) should be used for downloading from GitHub projects.
|
|
##
|
|
## ## Examples
|
|
##
|
|
## * [apr](https://github.com/Microsoft/vcpkg/blob/master/ports/apr/portfile.cmake)
|
|
## * [fontconfig](https://github.com/Microsoft/vcpkg/blob/master/ports/fontconfig/portfile.cmake)
|
|
## * [openssl](https://github.com/Microsoft/vcpkg/blob/master/ports/openssl/portfile.cmake)
