Do you question *whether* install lapi/*.h or *where* to install them?
We install include/*.h files. What is a difference with include/lapi/?

I'd say either install both or none. I would prefer to not install any,
LTP library is not separated anyway (there is an old Andrea's effort, but that
uses meson anyway). Installation was added in 2008 and I doubt anybody is using
it.

Sure not. Do we really want to check generate_arch.sh and generate_syscalls.sh
in arch? If yes, sure it needs to be added, but that was not my intention when
creating #1262. I really wanted to check C (and shell) library and tests code.

Kind regards,
