## Environment and Configuration
|
|
|
|
### Environment Variables
|
|
|
|
#### VCPKG_DOWNLOADS
|
|
|
|
This environment variable can be set to an existing directory to use for storing downloads instead of the internal
|
|
`downloads/` directory. It should always be set to an absolute path.
|
|
|
|
#### VCPKG_FEATURE_FLAGS
|
|
|
|
This environment variable can be set to a comma-separated list of off-by-default features in vcpkg. These features are
|
|
subject to change without notice and should be considered highly unstable.
|
|
|
|
Non-exhaustive list of off-by-default features:
|
|
|
|
- `binarycaching`
|
|
- `manifest`
|
|
|
|
#### EDITOR
|
|
|
|
This environment variable can be set to the full path of an executable to be used for `vcpkg edit`. Please see
|
|
`vcpkg help edit` for command-specific help.
|
|
|
|
#### VCPKG_ROOT
|
|
|
|
This environment variable can be set to a directory to use as the root of the vcpkg instance. Note that mixing vcpkg
|
|
repo versions and executable versions can cause issues.
|
|
|
|
#### VCPKG_VISUAL_STUDIO_PATH
|
|
|
|
This environment variable can be set to the full path to a Visual Studio instance on the machine. This Visual Studio instance
|
|
will be used if the triplet does not override it via the [`VCPKG_VISUAL_STUDIO_PATH` triplet setting](triplets.md#VCPKG_VISUAL_STUDIO_PATH).
|
|
|
|
Example: `D:\2017`
|
|
|
|
#### VCPKG_DEFAULT_TRIPLET
|
|
|
|
This environment variable can be set to a triplet name which will be used for unqualified triplet references in command lines.
|
|
|
|
#### VCPKG_OVERLAY_PORTS
|
|
|
|
This environment variable allows users to override ports with alternate versions according to the
|
|
[ports overlay](../specifications/ports-overlay.md) specification. List paths to overlays using
|
|
the platform dependent PATH seperator (Windows `;` | others `:`)
|
|
|
|
Example (Windows): `C:\custom-ports\boost;C:\custom-ports\sqlite3`
|
|
|
|
#### VCPKG_OVERLAY_TRIPLETS
|
|
|
|
This environment variable allows users to add directories to search for triplets.
|
|
[Example: overlay triplets](../examples/overlay-triplets-linux-dynamic.md).
|
|
List paths to overlays using the platform dependent PATH seperator (Windows `;`, others `:`)
|
|
|
|
#### VCPKG_FORCE_SYSTEM_BINARIES
|
|
|
|
This environment variable, if set, suppresses the downloading of CMake and Ninja and forces the use of the system binaries.
|
|
|
|
#### VCPKG_KEEP_ENV_VARS
|
|
|
|
This environment variable can be set to a list of environment variables, separated by `;`, which will be propagated to
|
|
the build environment.
|
|
|
|
Example: `FOO_SDK_DIR;BAR_SDK_DIR`
|
