Greetings!

Rebuilding for a prefix of /usr would be simpler, but here's what you 
would want to do:

1 - move man pages to /usr/share/man

2 - for headers, /usr/include

3 - libraries: Move to /lib, create a symlink:

ln -sv ../../lib/libf2fs.so.6.0.0 /usr/lib/libf2fs.so

ln -sv ../../lib/libf2fs_format.so.5.0.0 /usr/lib/libf2fs_format.so

4 - for binaries, move to /sbin

5 - as you mentioned, remove the *.la files


This is the best approach IMO
