/*
  On MSWindows platforms, one of these defines must always be set when
  building application programs:

   - "SOQT_DLL", when the application programmer is using the
     library in the form of a dynamic link library (DLL)

   - "SOQT_NOT_DLL", when the application programmer is using the
     library in the form of a static object library (LIB)

  Note that either SOQT_DLL or SOQT_NOT_DLL _must_ be defined by
  the application programmer on MSWindows platforms, or else the
  #error statement will hit. Set up one or the other of these two
  defines in your compiler environment according to how the library
  was built -- as a DLL (use "SOQT_DLL") or as a LIB (use
  "SOQT_NOT_DLL").

  (Setting up defines for the compiler is typically done by either
  adding something like "/DSOQT_DLL" to the compiler's argument
  line (for command-line build processes), or by adding the define to
  the list of preprocessor symbols in your IDE GUI (in the MSVC IDE,
  this is done from the "Project"->"Settings" menu, choose the "C/C++"
  tab, then "Preprocessor" from the dropdown box and add the
  appropriate define)).

  It is extremely important that the application programmer uses the
  correct define, as using "SOQT_NOT_DLL" when "SOQT_DLL" is
  correct is likely to cause mysterious crashes.
