Whether to add a compile flag to hide symbols of inline functions

The VISIBILITY_INLINES_HIDDEN property determines whether a flag for hiding symbols for inline functions, such as -fvisibility-inlines-hidden, should be used when invoking the compiler. This property only has an affect for libraries and executables with exports. This property is initialized by the value of the CMAKE_VISIBILITY_INLINES_HIDDEN if it is set when a target is created.
