Technically true, but things rapidly get confusing for distributors
(Debian, etc.) if files in a single package are covered by multiple

Therefore, to avoid any such problems we should not mix licenses in libzmq,
i.e. stay with the current status where the contents of the core libzmq
package are licensed in their entirety[*] under the same terms (LGPL v3 +
static linking exception).

[*] with the exception of the included OpenPGM library, since this is
included verbatim and not used by distributors anyway)

The other issue with CMake is obviously the extra maintenance involved. We
can see that there have been a couple of mostly one-off efforts to provide
a CMake build but until someone steps up to actually maintain such a build
there's no point in making it "official".
