I'm almost sure that when invoked on itself like:

cpack -G TGZ

cpack does not build at all.
cpack does install but AFAIK it does not trigger the build.

you can try:

ninja clean
cpack -V -G TGZ

and I'm pretty sure CPack will fail because it won't find the expected bits
to be installed precisely because they are not built.

Note that using "-V" verbose option of CPack you'll more traces of what
CPack does.

If you observe that could you send us a stripped down project that exhibit
this behavior?
