# 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.
|
||
|
|
|
||
|
