[Cmake] bug in cmDSWWriter

[Sebastien BARRE]

cmDSWWriter does not seem to take into account custom targets that were 
added with the ALL flag:

ADD_CUSTOM_TARGET(Name [ALL] command arg arg arg ...)
The ALL option is optional. If it is specified it indicates that this 
target should be added to the build all target.

You can reproduce it by locally changing:
   ADD_CUSTOM_TARGET(DoxygenDoc
to
   ADD_CUSTOM_TARGET(DoxygenDoc ALL
in
CMake\Utilities\Doxygen\CMakeLists.txt

run Cmake.

In Cmake.dsw, look at:
Project: "ALL_BUILD"=.\ALL_BUILD.dsp - Package Owner=<4>

you won't see DoxygenDoc

It might have something to do with code in cmDSWWriter.cxx located below 
that comment:

        // if this is the special ALL_BUILD utility, then
         // make it depend on every other non UTILITY project.
         // This is done by adding the names to the GetUtilities
         // vector on the makefile

Am I missing something ?
