So what are the actual benefits of namespacing the exported targets
associated with libraries?
On the consumer side it makes linking to targets less error prone.
When you link to a library target without a namespace and e.g. get the name
or scope wrong CMake will silently assume that you want to link a library by
name (e.g. in context of gcc "foo" becomes "-lfoo").
When the library and its headers happens to be in the compiler's standard
search directories this might not even get caught at build time right away.
When the library target has a namespace CMake will require the given name to
be a target and will fail during generation if the target is not actually
available.
Hi Nils:
Thanks for that explanation which convinced me this particular "best
practice" is worth implementing along with the rest mentioned in
<https://pabloariasal.github.io/2018/02/19/its-time-to-do-cmake-right/>.
