A shared library includes the code for the associated .mtb file, and the library can be shared by multiple applications in the same directory structure or workspace. When creating a new application, BSPs/libraries can be shared and placed in an mtb_shared directory adjacent to the application directory(ies), based on the "default_location" in the manifest file. When you add a BSP/library and specify it as shared, it is also included in the mtb_shared directory. These BSPs/libraries do not need to be checked into source control. All the code can be re-downloaded at any time from the information in the .mtb file.
You can change the name and location of the shared directory using make variables
CY_GETLIBS_SHARED_NAME and CY_GETLIBS_SHARED_PATH. For
