Interesting, thanks for sharing this! Static builds are also interesting for 
deployment by application bundles (such as APKs on Android), so I'd very much 
like to see the necessary changes to go upstream eventually :)

Regarding the transitive dependency issue, I think the cleaner and easier to 
use way is to not add them conditionally to each consuming module, but let the 
CMake config files of the module bringing in that transitive dependency search 
for them. Ie. like https://phabricator.kde.org/
R174:085ac943d0c00dd1d88650ab27c737b709870d9b, but possibly conditional for 
static builds.

Most of them should cross-build, but not all of them follow the canonical 
approach with KF5_HOST_TOOLING yet. The Yocto recipes for KF5 (https://
phabricator.kde.org/source/yocto-meta-kf5/browse/master/recipes-kf5/) might 
contain useful hints on how to cross-compile a given framework.
