This file defines the following variabls which are commonly needed or used in portfiles:
|
|
|
|
```cmake
|
|
VCPKG_TARGET_IS_<target> with <target> being one of the following: WINDOWS, UWP, LINUX, OSX, ANDROID, FREEBSD, OPENBSD. only defined if <target>
|
|
VCPKG_HOST_IS_<target> with <host> being one of the following: WINDOWS, LINUX, OSX, FREEBSD, OPENBSD. only defined if <host>
|
|
VCPKG_HOST_PATH_SEPARATOR Host specific path separator (USAGE: "<something>${VCPKG_HOST_PATH_SEPARATOR}<something>"; 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
|
|
VCPKG_SYSTEM_LIBRARIES list of libraries are provide by the toolchain and are not managed by vcpkg
|
|
TARGET_TRIPLET the name of the current triplet to build for
|
|
CURRENT_INSTALLED_DIR the absolute path to the installed files for the current triplet
|
|
HOST_TRIPLET the name of the triplet corresponding to the host
|
|
CURRENT_HOST_INSTALLED_DIR the absolute path to the installed files for the host triplet
|
|
VCPKG_CROSSCOMPILING Whether vcpkg is cross-compiling: in other words, whether TARGET_TRIPLET and HOST_TRIPLET are different
|
|
```
|
|
|
|
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.
