The build directory should be a symbolic link to the relevant kernel source tree. If it doesn't exist, you can create it with ln, e.g.
ln -s /usr/src/linux-220.127.116.11 /lib/modules/18.104.22.168/build,
assuming the source is in /usr/src/linux-22.214.171.124 of course. If you don't have modules for your 126.96.36.199 kernel, then I'm not sure, because perhaps /lib/modules/188.8.131.52 won't exist. In that case, you could try creating it and see if that works.
