# MACHO_COMPATIBILITY_VERSION

What compatibility version number is this target for Mach-O binaries.

For shared libraries on Mach-O systems (e.g. macOS, iOS) the `MACHO_COMPATIBILITY_VERSION` property correspond to `compatibility version` and `MACHO_CURRENT_VERSION` to `current version`. See the `FRAMEWORK` target property for an example.

Versions of Mach-O binaries may be checked with the `otool -L <binary>` command. If `MACHO_COMPATIBILITY_VERSION` is not set, the value of the `SOVERSION` property will be used.
