Tony Theodore 64989f688a CMake improvements, MinGW compatibility, shared libs support
* mingw-w64 fixes

  - `WIN32` is user-defined, `_WIN32` is pre-defined by toolchain[1]
  - use gcc options instead of MSVC
    - `-fPIC` is redundant on mingw
    - don't error on `old-style-cast`

[1] https://msdn.microsoft.com/en-us/library/b0084kay.aspx

* add option to build shared libs

* add option to disable command line tools

* ignore more Visual Studio files

* enable shared builds on MSVC (with cmake >= 3.4)
