# AIX_SHARED_LIBRARY_ARCHIVE

Added in version 3.31.

On AIX, enable or disable creation of a shared library archive for a `SHARED` library target:

- If enabled, the shared object `.so` file is placed inside an archive `.a` file. This is the preferred convention on AIX.

  The shared object name in the archive encodes version information from the `SOVERSION` target property, if set, and otherwise from the `VERSION` target property, if set.

- If disabled, a plain shared object `.so` file is produced. This is consistent with other UNIX platforms.

This property defaults to `CMAKE_AIX_SHARED_LIBRARY_ARCHIVE` if that variable is set when a non-imported `SHARED` library target is created by `add_library()`. Imported targets must explicitly enable `AIX_SHARED_LIBRARY_ARCHIVE` if they import an AIX shared library archive.

Changed in version 4.0: For a non-imported target, if this property is not set, the default is enabled. See policy `CMP0182`.

In CMake 3.31, policy `CMP0182` did not exist, so the default was disabled.

In CMake 3.30 and lower, `AIX_SHARED_LIBRARY_ARCHIVE` did not exist, so the default was disabled.
