The reason is a weird combination of dllimport/dllexport by OCCT toolkits - seems to be by C functions first of all exported by __Standard_API/__Draw_API etc specific to Windows.

There is a special macros HAVE_NO_DLL which is intended to disable these dllimport/dllexport, however this macros is not defined by any build procedure, including CMake scripts.

    0029377: Configuration, CMake - linkage errors while using static OCCT libraries on Windows platform
    
    HAVE_NO_DLL is now defined when building Static libraries.
02Author
Patch is ready for review.

HAVE_NO_DLL should be also defined at application level to avoid linkage working like:
1>OccTest.obj : warning LNK4049: locally defined symbol ?HashCode@@YAHQEBDH@Z (int __cdecl HashCode(char const * const,int)) imported


It might be reasonable renaming macros HAVE_NO_DLL to OCCT_NO_DLL for consistency with other macros,
but this should be documented change since, apparently, some advanced users are already using it.

Making a "Static" build with HAVE_NO_DLL also reduces building time from 00:20:54 to 00:16:51.

Reviewed, please integrate.

Other corrections related to static builds should be made within #22651
