* 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.

also use `-lpthread`, but there are potential issues with ordering of command

If you're running benchmarks on Windows, the shlwapi library (`-lshlwapi`) is
also required.
### Building with Visual Studio 2015 or 2017
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.
#ifdef _WIN32
#pragma comment ( lib, "Shlwapi.lib" )
#ifdef _DEBUG
#pragma comment ( lib, "benchmarkd.lib" )
#else
#pragma comment ( lib, "benchmark.lib" )
#endif
#endif
```
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.
### Building with Intel 2015 Update 1 or Intel System Studio Update 4
See instructions for building with Visual Studio. Once built, right click on the solution and change the build to Intel.
### Building on Solaris
If you're running benchmarks on solaris, you'll want the kstat library linked in
too (`-lkstat`).
