## # vcpkg_extract_source_archive
|
|
##
|
|
## Extract an archive into the source directory.
|
|
##
|
|
## ## Usage
|
|
## ```cmake
|
|
## vcpkg_extract_source_archive(
|
|
## <${ARCHIVE}> [<${TARGET_DIRECTORY}>]
|
|
## )
|
|
## ```
|
|
## ## Parameters
|
|
## ### ARCHIVE
|
|
## The full path to the archive to be extracted.
|
|
##
|
|
## This is usually obtained from calling [`vcpkg_download_distfile`](vcpkg_download_distfile.md).
|
|
##
|
|
## ### TARGET_DIRECTORY
|
|
## If specified, the archive will be extracted into the target directory instead of `${CURRENT_BUILDTREES_DIR}\src\`.
|
|
##
|
|
## This can be used to mimic git submodules, by extracting into a subdirectory of another archive.
|
|
##
|
|
## ## Notes
|
|
## This command will also create a tracking file named <FILENAME>.extracted in the TARGET_DIRECTORY. This file, when present, will suppress the extraction of the archive.
|
|
##
|
|
## ## Examples
|
|
##
|
|
## * [libraw](https://github.com/Microsoft/vcpkg/blob/master/ports/libraw/portfile.cmake)
|
|
## * [protobuf](https://github.com/Microsoft/vcpkg/blob/master/ports/protobuf/portfile.cmake)
|
|
## * [msgpack](https://github.com/Microsoft/vcpkg/blob/master/ports/msgpack/portfile.cmake)
