ADD_LIBRARY(mylib SHARED src1.cxx src2.cxx ...)

Make sure the source files use __declspec(dllexport) tags.  You can test
for the definition mylib_EXPORTS in the preprocessor to switch between
__declspec(dllexport) and __declspec(dllimport) appropriately in header
files.  Alternatively you can use a .def file by adding it as a source file.
