Custom builds should always use /usr/local, /usr is reserved for the
system provided software as documented in the Filesystem Hierarchy
Standard:
"
The /usr/local hierarchy is for use by the system administrator when
installing software locally. It needs to be safe from being
overwritten when the system software is updated. It may be used for
programs and data that are shareable amongst a group of hosts, but not
found in /usr.
Locally installed software must be placed within /usr/local rather
than /usr unless it is being installed to replace or upgrade software
in /usr. [27]
[27] Software placed in / or /usr may be overwritten by system
upgrades (though we recommend that distributions do not overwrite
data in /etc under these circumstances). For this reason, local
software must not be placed outside of /usr/local without good
reason.

The routino library for custom builds should be installed in
/usr/local/lib or preferably its Multi-Arch subdirectory.
To have the library found by other programs you need to add the
/usr/local/lib directory to the search paths in /etc/ld.so.conf.
On Debian/Ubuntu you can drop in a configuration sniplet in
/etc/ld.so.conf.d for the local configuration:
$ cat /etc/ld.so.conf.d/usr-local.conf
/usr/local/lib
If you use the Multi-Arch library paths you need to append the paths to
the 32 & 64bit library path configurations:
/etc/ld.so.conf.d/i386-linux-gnu.conf
/etc/ld.so.conf.d/x86_64-linux-gnu.conf
These need to have respectively /usr/local/lib/i386-linux-gnu and
/usr/local/lib/x86_64-linux-gnu appended, preferably with a comment to
help you merge the configuration changes on upgrade, e.g.:
$ cat /etc/ld.so.conf.d/x86_64-linux-gnu.conf
# Multiarch support
/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu
# Custom local libraries
/usr/local/lib/x86_64-linux-gnu
Kind Regards,
Bas
