'module_name': cannot specify different idl_module attributes in a project
idl_module attributes with the same name but different dllname or version parameters were found in two of the files in a compilation. Only one unique idl_module attribute can be specified per compilation.
Identical idl_module attributes can be specified in more than one source code file.
For example, if the following idl_module attributes were found:
// 1.cpp [ idl_module(name="x", dllname="file.dll", version="1.1") ]; // 2.cpp [ idl_module(name="x", dllname="file.dll", version="1.0") ];
the compiler would generate C3172 (note the different version values).
