Allow override of BUILD_SHARED_LIBS The cmake option BUILD_SHARED_LIBS is a cmake built-in option to control if libraries are by default SHARED or STATIC. For large projects, it is desired to be able to design gtsam as a shared or static library regardless of the value of BUILD_SHARED_LIBS. This change is unobtrusive, two new cmake options are created, to force gtsam to be a shared or static library. If neither option is set (this is the default), the behavior of gtsam remains unchanged which is to use BUILD_SHARED_LIBS decision.
