Handle a dot character in project name correctly

A dot is not interpreted corrected in project names. For a project name like 'abc.def', the generated dll is 'abc.dll' instead of 'abc.def.dll'. Affects the output of both static and shared libraries. Haven't been confirmed for applications.

Reproduce the issue with a project named `abc.def` and compare the generated names for static and shared libraries. Check whether applications show the same behavior. Done means the generated library names preserve the complete project name, producing `abc.def.dll` rather than `abc.dll`.
