Addresses issue #634. (#866) 

* Update with instructions to build under Visual Studio

Fixes Issue #634.

I spent 3 days trying to build this library under Visual Studio 2017, only to discover on has to link to `Shlwapi.lib`.

Became so frustrated with the docs that I added full build instructions for Visual Studio 2015, 2017 and Intel Comiler 2015 and 2019.

The `shlwapi` library (`-lshlwapi`) is required to support a call to `CPUInfo` which reads the registry. Either add `shlwapi.lib` under `[ Configuration Properties > Linker > Input ]`, or use the following:
```
// Alternatively, can add libraries using linker options.

Can also use the graphical version of CMake:
* Open `CMake GUI`.
* Under `Where to build the binaries`, same path as source plus `build`.
* Under `CMAKE_INSTALL_PREFIX`, same path as source plus `install`.
* Click `Configure`, `Generate`, `Open Project`.
* If build fails, try deleting entire directory and starting again, or unticking options to build less.
