Hi,
this nice post
(https://crascit.com/2016/01/31/enhanced-source-file-handling-with-target_sources/)
mentions some modern usage of target_sources(), but also shows some
discrepancy between target_link_libraries and the remaining target_*
functions. In particlar, CMake does not allow linking to a target
outside its creation scope whereas all the other ones do. There exists a
workaround with include(), but it seems not the correct and clean way to
handle this.
So I think lifting this limitation would escepially help large-scale
projects and improve modularization by handling third-party dependencies
in the specific modules (as long as only this particular module needs it).
So what is your experience regarding this linking restriction,
especially in larger projects? I also opened an issue for this (see
https://gitlab.kitware.com/cmake/cmake/issues/17943).
Best regards,
Patrick Stotko
