And on another machine, the last report was
[144%] Built target plasmasimple
All were with CMake 2.8.10.2
I see from
http://www.cmake.org/pipermail/cmake/2007-June/014856.html
that this has happened in the past, and how it might happen.
In my case, it happened when I did
make -j4 all examples_noinst
Is the simple act of building the special 'all' target and a
target that uses EXCLUDE_FROM_ALL enough to trigger this
strange behavior? I haven't checked, but it's a tempting guess.

I've also seen this using the Makefile generator, the bigger problem is
that it ends up building the dependencies of those targets in parallel,
if there is overlap, it may try to build the same target multiple times
simultaneously, which can obviously break the build
The workaround is to add a (cmake) target that depends on the set of
targets you want to build in parallel.
