[CMake] Cmake hangs when a custom target for running cpack is added.

[Alexander Broekhuis]

Hi all,

Sorry to "hijack" this message, but I am running into the same problem. As
part of my build I create zip files, and currently have this coupled to a
normal library target (add_library). This works ok, but for some new
features I need to create a zip file with a collection of libraries, so
instead of coupling CPack to a library target I want to add it using a
custom target which is coupled to the build chain (using ALL).

How can I do this without running in the problem mentioned by the topic
starter? And what is the difference in this case between a normal
(add_library) target and a custom target?

Thanks!
