PRECOMPILED_TARGET
Use the PRECOMPILED_OBJ macro to override the default name given to the precompiled target.
By default, the Build utility uses the precompiled header with the precompiled #include setting that you specify (for example, precomp.h). The Build utility uses the precompiled header to create precomp.obj for the precompiled object and precomp.pch for the precompiled target.
You can override those names by setting the PRECOMPILED_OBJ and PRECOMPILED_TARGET macros.
