BUILD
(Project Properties window)
*.prj\BUILD
The BUILD group contains settings that link the object files created by the COMPILE, ASSEMBLE, and CUSTOM groups into an application program. This group invokes the linker after all other files have been checked for rebuild, so you can only have one BUILD group for a project.
The BUILD group also enables you to use prelink and postlink commands.
See the documentation for your toolchain for more information on the settings in this group.
