Environment and Configuration
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.
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:
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.
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.
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.
This environment variable can be set to a triplet name which will be used for unqualified triplet references in command lines.
This environment variable, if set, suppresses the downloading of CMake and Ninja and forces the use of the system binaries.
This environment variable can be set to a list of environment variables, separated by
;, which will be propagated to
the build environment.
