Ok now I think I get it.

AIFAIK, CPack does NOT run "all" target.

"make package" does.

You should be able to call CPack explicitely without problem, try:

cpack

in your build dir. However this won't try to build anything.

> It could be that a target doesn't build because of compile or link errors and are not an install target (unit tests for example or other sub projects which are not required).

You'll build a package with a failing unit test !! :-]

> CPack should build as much as possible and only break if an install target has errors.

Like I said, CPack does not build anything per se, the "package"
target depends on "all"
so that the build tool (make,  Visual Studio, XCode etc...) does build all.

> Currently it is not possible to run cpack and create packages for such situation.

True but I'm not sure I would personnally want to build a package out
of a partially buildable project.
Other may have other opinion though.
