vcpkg_download_distfile

The latest version of this document lives in the vcpkg repo.

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

vcpkg_download_distfile(
    <OUT_VARIABLE>
    URLS <http://mainUrl> <http://mirror1>...
    FILENAME <output.zip>
    SHA512 <5981de...>
    [ALWAYS_REDOWNLOAD]
)

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 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.

QUIET

Suppress output on cache hit

SKIP_SHA512

Skip SHA512 hash check for file.

This switch is only valid when building with the --head command line flag.

ALWAYS_REDOWNLOAD

Avoid caching; this is a REST call or otherwise unstable.

Requires SKIP_SHA512.

HEADERS

A list of headers to append to the download request. This can be used for authentication during a download.

Headers should be specified as ": ".

Notes

The helper vcpkg_from_github should be used for downloading from GitHub projects.

Examples
