| SOVERSION |
| --------- |
| |
| What version number is this target. |
| |
| For shared libraries :prop_tgt:`VERSION` and ``SOVERSION`` can be used to |
| specify the build version and API version respectively. 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 corresponds to *compatibility version* and |
| :prop_tgt:`VERSION` 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. |
