  When using Autoconf configure script, BuildMagickModules is defined by

  requires that support for shared libraries be enabled.

  When using Visual Studio and when using the Autoconf configure script with
  MinGW these options are supplied when compiling the associated components:

    libMagick:           _DLL _MAGICKMOD_ _MAGICKLIB_
    module:              _DLL
    executable/Magick++: _DLL _MAGICKMOD_

  The Visual Studio build only knows how to build a static build, or a DLL
  modules-based build.  The Autotools-based build knows how to build static,
  shared, and modules builds.

  Libtool's libltdl is required to build modules when the Autoconf configure
  script is used.
