Can you change to windows 10? If you are on 10, you can turn the restriction off. Otherwise, I believe there's complicated ways to shorten the path.

The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters.    processor_withAVeryVeryLongName    C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Microsoft.CppBuild.targets    312
