Portfile variable reference

  • Article

These are variables set automatically by vcpkg for use in any port. They should not be modified by the port.

Full list of variables is defined in the vcpkg_common_definitions module.

PORT

The name of the port that is currently being built.

VERSION

The version of the port that is currently being built.

Does not contain the "port-version".

VCPKG_TARGET_IS_<system>

Defined to a true value if building for <system>.

Supported systems:

  • VCPKG_TARGET_IS_WINDOWS (also true for UWP and MinGW)
  • VCPKG_TARGET_IS_UWP
  • VCPKG_TARGET_IS_MINGW
  • VCPKG_TARGET_IS_LINUX
  • VCPKG_TARGET_IS_OSX
  • VCPKG_TARGET_IS_IOS
  • VCPKG_TARGET_IS_ANDROID
  • VCPKG_TARGET_IS_FREEBSD
  • VCPKG_TARGET_IS_OPENBSD
  • VCPKG_TARGET_IS_EMSCRIPTEN

VCPKG_HOST_IS_<system>

Defined to a true value if building on <system>.

Supported systems:

  • VCPKG_HOST_IS_WINDOWS
  • VCPKG_HOST_IS_OSX
  • VCPKG_HOST_IS_LINUX
  • VCPKG_HOST_IS_FREEBSD
  • VCPKG_HOST_IS_OPENBSD

VCPKG_HOST_PATH_SEPARATOR

Host specific path separator.

Always use quotes when expanding VCPKG_HOST_PATH_SEPARATOR since it may contain a semicolon. For example:

set(ENV{SOMEPATH} "$ENV{SOMEPATH}${VCPKG_HOST_PATH_SEPARATOR}${my_extra_path}")

VCPKG_HOST_EXECUTABLE_SUFFIX

Executable suffix for the building system.

This is set to ".exe" on Windows and "" on other platforms.

VCPKG_TARGET_EXECUTABLE_SUFFIX

Executable suffix for the built-for system.

This is set to ".exe" when VCPKG_TARGET_IS_WINDOWS and "" otherwise.

VCPKG_HOST_BUNDLE_SUFFIX

Bundle suffix of the building system.

VCPKG_TARGET_BUNDLE_SUFFIX

Bundle suffix of the built-for system.

VCPKG_TARGET_STATIC_LIBRARY_PREFIX

Static library prefix for the built-for system.

See also CMAKE_STATIC_LIBRARY_PREFIX.

VCPKG_TARGET_STATIC_LIBRARY_SUFFIX

Static library suffix for the built-for system.

See also CMAKE_STATIC_LIBRARY_SUFFIX.

VCPKG_TARGET_SHARED_LIBRARY_PREFIX

Shared (dynamic) library prefix for the built-for system.

See also CMAKE_SHARED_LIBRARY_PREFIX.

VCPKG_TARGET_SHARED_LIBRARY_SUFFIX

Shared (dynamic) library suffix for the built-for system.

See also CMAKE_SHARED_LIBRARY_SUFFIX.

VCPKG_TARGET_IMPORT_LIBRARY_PREFIX

Import library prefix for the built-for system.

See also CMAKE_IMPORT_LIBRARY_PREFIX.

VCPKG_TARGET_IMPORT_LIBRARY_SUFFIX

Import library suffix for the built-for system.

See also CMAKE_IMPORT_LIBRARY_SUFFIX.

VCPKG_FIND_LIBRARY_PREFIXES

Prefixes used for find_library() calls in portfiles.

These are set to

VCPKG_FIND_LIBRARY_SUFFIXES

Suffixes used for find_library() calls in portfiles.

TARGET_TRIPLET

The name of the triplet being built for.

CURRENT_INSTALLED_DIR

The absolute path to the installed files for the target triplet.

HOST_TRIPLET

The name of the triplet that matches the building system.

CURRENT_HOST_INSTALLED_DIR

The absolute path to the installed files for the host triplet.

VCPKG_CROSSCOMPILING

Whether vcpkg is compiling for a different system than the building machine.

This is the same as comparing TARGET_TRIPLET and HOST_TRIPLET for equality. If the triplets are different, ports must not assume that they can run the results of a build.

For example, when compiling for Android from MacOS, VCPKG_CROSSCOMPILING will be set to a true value.
