/* Shared libraries are messy in Visual Studio. We have to distinguish three
 * cases:
 *   (1) this header is being used to build the simmath shared library (dllexport)
 *   (2) this header is being used by a *client* of the simmath shared
 *       library (dllimport)
 *   (3) we are building the simmath static library, or the client is
 *       being compiled with the expectation of linking with the
 *       simmath static library (nothing special needed)
 * In the CMake script for building this library, we define one of the symbols
 *     SIMMATH_BUILDING_{SHARED|STATIC}_LIBRARY
 * Client code normally has no special symbol defined, in which case we'll
 * assume it wants to use the shared library. However, if the client defines
 * the symbol SimTK_USE_STATIC_LIBRARIES we'll suppress the dllimport so
 * that the client code can be linked with static libraries. Note that
 * the client symbol is not library dependent, while the library symbols
 * affect only the simmath library, meaning that other libraries can
 * be clients of this one. However, we are assuming all-static or all-shared.
