Summary:                    CheckStructHasMember generates an uninitialized
variable warning
Description: 
Related to bug 15203 (which is fixed in CMake 3.2).

The current check_struct_has_member macro (as can be found in CMake 3.2)
generates an uninitialized variable warning (noticeable via Clangs static code
analyzer).

A patch was proposed in http://www.cmake.org/Bug/view.php?id=15203#c37979, but a
valid concern was raised about invoking C++ constructors. Here is a new minimal
patch which uses sizeof instead.
