Project was skipped when rebuild the solution in Visual studio

0. Environment

Windows 8 Pro and Enterprice

1. Problem

I am working on a solution which contains C# projects and C++ projects. The C++ projects is not builded (or just say they are skipped) when I rebuild all of the solution. I get the build result: "Rebuild All: 9 succeeded, 0 failed, 2 skipped", the 2 skipped projects are C++ projects

2. Solution

Build -> Configuration Manager -> Ticke the Build option
