target,TARGETTYPE

Use the TARGETTYPE macro to specify the type of product being built. TARGETTYPE gives the Build utility clues about some of the input files that it should expect. You must include this macro in your Sources file.
When you build a DLL, TARGETTYPE is typically LIBRARY or DYNLINK.
The full list of possible values is as follows.
Value Definition ProductExtension
PROGRAM
A user-mode program that does not export anything.
.exe
PROGLIB
An executable program that also exports functions for other programs.
.exe
DYNLINK
A dynamic-link library (DLL). This could be a control panel program or any other program that can be dynamically loaded. A dynamic-link library exports functions that other binaries can link to. The DLL switch is passed to the linker to indicate that the build product isnot a stand-alone .exe. When you build a dynamic-link library, you might also need to set the TARGETEXT macro.
.dll
LIBRARY
A user-mode import library that contains code that will be linked with other code. This is a library of objects, not an import library. It contains routines to which other components can link statically. (An import library is built as a side effect of building a dynamic-link library. Whenever you build a DLL, you get a .lib file and a .dll file. When you build a library, you just get a .lib file.)
.lib
DRIVER_LIBRARY
A kernel-mode import library. This is the kernel-mode equivalent of LIBRARY. It contains routines to which other kernel-mode components can link statically.
.lib
DRIVER
A kernel-mode driver.
.sys
EXPORT_DRIVER
A kernel-mode driver that also exports functions for other drivers.
.sys
MINIPORT
A kernel-mode driver that does not link with ntoskrnl.lib or hal.lib.
.sys
GDI_DRIVER
A kernel-mode graphics driver that links with win32k.sys.
.dll
BOOTPGM
A kernel-mode driver.
.exe
HAL
The hardware abstraction layer.
.dll
NOTARGET
Specifies that no target should actually be created. Use this if you have a directory that needs some processing, but you do not want a binary to be generated.
