- * Shared libraries are messy in Visual Studio. We have to distinguish three
- * cases:
- * (1) this header is being used to build the Lepton shared library
- * (dllexport)
- * (2) this header is being used by a *client* of the Lepton shared
- * library (dllimport)
- * (3) we are building the Lepton static library, or the client is
- * being compiled with the expectation of linking with the
- * Lepton static library (nothing special needed)
- * In the CMake script for building this library, we define one of the symbols
- * Lepton_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 LEPTON_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 Lepton library, meaning that other libraries can
- * be clients of this one. However, we are assuming all-static or all-shared.
