| VERSION |
| ------- |
| |
| What version number is this target. |
| |
| For shared libraries ``VERSION`` and :prop_tgt:`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. For |
| executables ``VERSION`` can be used to specify the build version. When |
| building or installing appropriate symlinks are created if the |
| platform supports symlinks. |
| |
| Windows Versions |
| ^^^^^^^^^^^^^^^^ |
| |
| For shared libraries and executables on Windows the ``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 ``VERSION`` property is a fallback to :prop_tgt:`MACHO_CURRENT_VERSION` |
| property which corresponds to *current version* and :prop_tgt:`SOVERSION` |
| is a fallback to :prop_tgt:`MACHO_COMPATIBILITY_VERSION` which corresponds |
| to *compatiblity 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. |
