Just finished porting VS CSharp solution to CMake 3.8 build system. Works fairly well except for Interop reference assemblies that must be embedded (like Microsoft.Office.Interop.Excel). The reference assembly can be added but there is no way to enable the "Embed Interop Types" and "Specific Version" properties for the added Interop reference assembly. This results in build errors for CSharp applications that require this feature.
