For future reference, one can determine what triggered the reconfigure

It appears not to be enough to have configured with
-DCMAKE_VERBOSE_MAKEFILE:BOOL=TRUE.
In our case, for reasons we have not yet figured out, the depend
file for a particular .cu.o object built for a test was what was newer
and causing the rebuild. For so-far not understood reasons, this
I am guessing the behaviour has nothing to do with the "install" target
but rather the default "all" target which "install" depends on as well.
Hence you should see the same behaviour when running plain "make" twice.
FindCUDA.cmake forces reconfiguration so dependencies generated at build
time can be reprocessed:
