vcpkg_extract_source_archive
The latest version of this document lives in the vcpkg repo.
Extract an archive into the source directory.
Usage
There are two "overloads" of this function. The first is deprecated:
vcpkg_extract_source_archive(<${ARCHIVE}> [<${TARGET_DIRECTORY}>])
This overload should not be used.
The latter is suggested to use for all future vcpkg_extract_source_archives.
vcpkg_extract_source_archive(<out-var>
ARCHIVE <path>
[NO_REMOVE_ONE_LEVEL]
[SKIP_PATCH_CHECK]
[PATCHES <patch>...]
[SOURCE_BASE <base>]
[BASE_DIRECTORY <relative-path> | WORKING_DIRECTORY <absolute-path>]
)
vcpkg_extract_source_archive takes an archive and extracts it.
It replaces existing uses of vcpkg_extract_source_archive_ex.
The simplest use of it is:
vcpkg_download_distfile(archive ...)
vcpkg_extract_source_archive(source_path ARCHIVE "${archive}")
The general expectation is that an archives are laid out with a base directory, and all the actual files underneath that directory; in other words, if you extract the archive, you'll get something that looks like:
zlib-1.2.11/
doc/
...
examples/
...
ChangeLog
CMakeLists.txt
README
zlib.h
...
vcpkg_extract_source_archive automatically removes this directory,
and gives you the items under it directly. However, this only works
when there is exactly one item in the top level of an archive.
Otherwise, you'll have to pass the NO_REMOVE_ONE_LEVEL argument to
prevent vcpkg_extract_source_archive from performing this transformation.
If the source needs to be patched in some way, the PATCHES argument
allows one to do this, just like other vcpkg_from_* functions.
Additionally, the SKIP_PATCH_CHECK is provided for --head mode -
this allows patches to fail to apply silently.
This argument should only be used when installing a --head library,
since otherwise we want a patch failing to appply to be a hard error.
vcpkg_extract_source_archive extracts the files to
${CURRENT_BUILDTREES_DIR}/<base-directory>/<source-base>-<hash>.clean.
When in editable mode, no .clean is appended,
to allow for a user to modify the sources.
base-directory defaults to src,
and source-base defaults to the stem of <archive>.
You can change these via the BASE_DIRECTORY and SOURCE_BASE arguments
respectively.
If you need to extract to a location that is not based in CURRENT_BUILDTREES_DIR,
you can use the WORKING_DIRECTORY argument to do the same.
