When building or +installing appropriate symlinks are created if the platform supports +symlinks and the linker supports so-names. If only one of both is +specified the missing is assumed to have the same version number. +``SOVERSION`` is ignored if :prop_tgt:`NO_SONAME` property is set. + +Windows Versions +^^^^^^^^^^^^^^^^ + +For shared libraries and executables on Windows the :prop_tgt:`VERSION` +attribute is parsed to extract a ``<major>.<minor>`` version number. +These numbers are used as the image version of the binary. + +Mach-O Versions +^^^^^^^^^^^^^^^ + +For shared libraries and executables on Mach-O systems (e.g. macOS, iOS), +the ``SOVERSION`` property is a fallback to +:prop_tgt:`MACHO_COMPATIBILITY_VERSION` property which corresponds to +*compatiblity version* and :prop_tgt:`VERSION` is a fallback to +:prop_tgt:`MACHO_CURRENT_VERSION` which corresponds to *current version*. +See the :prop_tgt:`FRAMEWORK` target property for an example. Versions +of Mach-O binaries may be checked with the ``otool -L <binary>`` command. |
