Unfortunately, I have approximately 100 targets all with the same output name(simple) but in CMake I give them all unique target names(dot separated name built from their place in the directory tree).  This works fine for Makefiles however the ninja generator seems to be adding:

Not currently.  There are a few other projects I am aware of that
do something similar.  I will probably modify the generator to not
output shortcut targets for a given basename if more than one target
has that basename.
