I stumbled upon a tiny problem with your solution:
make now complains with the following warning:
gmake[4]: warning: jobserver unavailable: using -j1.  Add `+' to parent
make rule.

I checked the generated file ./test/CMakeFiles/check.dir/build.make and
found the line that causes this warning:

  cd /export/home/loose/work/hello/build/test && /usr/bin/gmake test

It is caused by the fact that make is called as /usr/bin/gmake, instead
of $(MAKE) which is recommended by the GNU Make manual. (See  
http://www.gnu.org/software/automake/manual/make/Error-Messages.html and
http://www.gnu.org/software/automake/manual/make/MAKE-Variable.html#MAKE-Variable)

I guess that /usr/bin/gmake has been put there as result of the
expansion of CMAKE_BUILD_TOOL. Would there be a workaround?
