AIX_EXPORT_ALL_SYMBOLSΒΆ
Added in version 3.17.
On AIX, CMake automatically exports all symbols from shared libraries, and
from executables with the ENABLE_EXPORTS target property set.
Explicitly disable this boolean property to suppress the behavior and
export no symbols by default. In this case it is expected that the project
will use other means to export some symbols.
This property is initialized by the value of
the CMAKE_AIX_EXPORT_ALL_SYMBOLS variable if it is set
when a target is created.
