## # vcpkg_common_definitions
##
## File contains helpful variabls for portfiles which are commonly needed or used.
##
## ## The following variables are available:
## ```cmake
## VCPKG_TARGET_IS_<target> with <target> being one of the following: WINDOWS, UWP, LINUX, OSX, ANDROID, FREEBSD. only defined if <target>
## VCPKG_HOST_PATH_SEPARATOR Host specific path separator
## VCPKG_HOST_PATH_SEPARATOR_ESCAPED Escaped version of VCPKG_HOST_PATH_SEPARATOR if necessary (e.g. symbol with special meaning in cmake like ";")
## 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)
## ```
##
## CMAKE_STATIC_LIBRARY_PREFIX, CMAKE_STATIC_LIBRARY_SUFFIX, CMAKE_SHARED_LIBRARY_PREFIX, CMAKE_SHARED_LIBRARY_SUFFIX are defined for the target so that
## portfiles are able to use find_library calls to discover dependent libraries within the current triplet for ports.
