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:
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.
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_DEFAULT_HOST_TRIPLET
This environment variable can be set to a triplet name which will be used for unqualified host port references in command lines and all host port references in dependency lists. See the host-dependencies documentation for more information.
VCPKG_OVERLAY_PORTS
This environment variable allows users to override ports with alternate versions according to the
ports overlay specification. List paths to overlays using
the platform dependent PATH separator (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.
List paths to overlays using the platform dependent PATH separator (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
VCPKG_MAX_CONCURRENCY
This environment variables limits the amount of concurrency requested by underlying buildsystems. If unspecified, this defaults to logical cores + 1.
VCPKG_DEFAULT_BINARY_CACHE
This environment variable redirects the default location to store binary packages. See Binary Caching for more details.
VCPKG_BINARY_SOURCES
This environment variable adds or removes binary sources. See Binary Caching for more details.
VCPKG_NUGET_REPOSITORY
This environment variable changes the metadata of produced NuGet packages. See Binary Caching for more details.
VCPKG_USE_NUGET_CACHE
This environment variable allows using NuGet's cache for every nuget-based binary source. See Binary Caching for more details.
X_VCPKG_ASSET_SOURCES
Note: This is an experimental feature and may change or be removed at any time
This environment variable allows using a private mirror for all SHA512-tagged assets. See Asset Caching for more details.
