# vcpkg_common_definitions File contains helpful variabls for portfiles which are commonly needed or used. ## The following variables are available: ```cmake VCPKG_TARGET_IS_ with being one of the following: WINDOWS, UWP, LINUX, OSX, ANDROID, FREEBSD. only defined if VCPKG_HOST_PATH_SEPARATOR Host specific path separator (USAGE: "${VCPKG_HOST_PATH_SEPARATOR}"; only use and pass variables with VCPKG_HOST_PATH_SEPARATOR within "") VCPKG_HOST_EXECUTABLE_SUFFIX executable suffix of the host VCPKG_TARGET_EXECUTABLE_SUFFIX executable suffix of the target VCPKG_TARGET_STATIC_LIBRARY_PREFIX static library prefix for target (same as CMAKE_STATIC_LIBRARY_PREFIX) VCPKG_TARGET_STATIC_LIBRARY_SUFFIX static library suffix for target (same as CMAKE_STATIC_LIBRARY_SUFFIX) VCPKG_TARGET_SHARED_LIBRARY_PREFIX shared library prefix for target (same as CMAKE_SHARED_LIBRARY_PREFIX) VCPKG_TARGET_SHARED_LIBRARY_SUFFIX shared library suffix for target (same as CMAKE_SHARED_LIBRARY_SUFFIX) VCPKG_TARGET_IMPORT_LIBRARY_PREFIX import library prefix for target (same as CMAKE_IMPORT_LIBRARY_PREFIX) VCPKG_TARGET_IMPORT_LIBRARY_SUFFIX import library suffix for target (same as CMAKE_IMPORT_LIBRARY_SUFFIX) VCPKG_FIND_LIBRARY_PREFIXES target dependent prefixes used for find_library calls in portfiles VCPKG_FIND_LIBRARY_SUFFIXES target dependent suffixes used for find_library calls in portfiles ``` CMAKE_STATIC_LIBRARY_(PREFIX|SUFFIX), CMAKE_SHARED_LIBRARY_(PREFIX|SUFFIX) and CMAKE_IMPORT_LIBRARY_(PREFIX|SUFFIX) are defined for the target Furthermore the variables CMAKE_FIND_LIBRARY_(PREFIXES|SUFFIXES) are also defined for the target so that portfiles are able to use find_library calls to discover dependent libraries within the current triplet for ports. ## Source [scripts/cmake/vcpkg_common_definitions.cmake](https://github.com/Microsoft/vcpkg/blob/master/scripts/cmake/vcpkg_common_definitions.cmake)
