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

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 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 should be used for downloading from GitHub projects.
