92  On MSWindows platforms, one of these defines must always be set when
93  building application programs:
94 
95  - "SOQT_DLL", when the application programmer is using the
96  library in the form of a dynamic link library (DLL)
97 
98  - "SOQT_NOT_DLL", when the application programmer is using the
99  library in the form of a static object library (LIB)
100 
101  Note that either SOQT_DLL or SOQT_NOT_DLL _must_ be defined by
102  the application programmer on MSWindows platforms, or else the
103  #error statement will hit. Set up one or the other of these two
104  defines in your compiler environment according to how the library
105  was built -- as a DLL (use "SOQT_DLL") or as a LIB (use
106  "SOQT_NOT_DLL").
107 
108  (Setting up defines for the compiler is typically done by either
109  adding something like "/DSOQT_DLL" to the compiler's argument
110  line (for command-line build processes), or by adding the define to
111  the list of preprocessor symbols in your IDE GUI (in the MSVC IDE,
112  this is done from the "Project"->"Settings" menu, choose the "C/C++"
113  tab, then "Preprocessor" from the dropdown box and add the
114  appropriate define)).
115 
116  It is extremely important that the application programmer uses the
117  correct define, as using "SOQT_NOT_DLL" when "SOQT_DLL" is
118  correct is likely to cause mysterious crashes.
