MS Visual C++ toolchain in Eclipse IDE

First, the procedure for installing Microsoft Visual C++ toolchain in Eclipse IDE and Windows 10 is presented.
Then, a C++ 32-bit HelloWorld project is implemented. Six paths must be included in the project before the executation of this simple program. We include these six paths for 64-bit C++ project into user environment variables of Windows 10. As a result, the setup of a C++ 64-bit HelloWorld project becomes simpler.
Finally, C++ 64-bit shared library svdComplexDevice1.dll is generated with Microsoft Visual C++ toochain in Eclipse IDE.

Visual Studio Community 2015 with update 3, x64 (Release date: 27/Jun/2016) is needed.
