This one SHOULD NOT be set for a NSIS/WIndows package

> SET(CPACK_SET_DESTDIR ON)

in fact beginning with CMake 2.8.6 it is seldom useful to set
CPACK_SET_DESTDIR to ON
in any case.

> INSTALL(TARGETS Adjustment RUNTIME DESTINATION ${BUILD_ROOT}/bin/install COMPONENT AdjustmentApp)
> INSTALL(TARGETS triage RUNTIME DESTINATION ${BUILD_ROOT}/bin/install COMPONENT triageApp)

if ${BUILD_ROOT} is an absolute path this won't work.

Trust me you don't want to set CPACK_SET_DESTDIR to ON.
In the same way "absolute DESTINATION install path" will NOT work on Windows.

Did you use the "Start" archive or did you use the "final":
http://www.cmake.org/Wiki/File:ComponentExample.zip

> The example is not working at all, NSIS got errors:

May be the example is not up to date, but using
http://www.cmake.org/Wiki/File:ComponentExample.zip
I can build an NSIS installer using CMake 2.8.8 and NSIS 2.46.
(on Linux with some crosstools but concerning the generated
 NSIS project and NSIS processing it looks just fine).

Are you using some custom build of NSIS ?
Like 64 bits
http://public.kitware.com/Bug/view.php?id=13203
or svn trunk?

if not it should work.
