--prefix should be in the 'containing directory' for all bins and
libraries.

That is   --prefix=/usr
is what you should have used.

you will find you now have a four sub-directories in /usr/bin
that will need to be cleaned up... eg
   /usr/bin/bin
   /usr/bin/lib
   /usr/bin/include
   /usr/bin/share

I do not and never have recommended any software package be directly
installed when it is not part of a package management system.
Any direct installed packages is best installed in a /opt sub-directory
such as   --prefix=/opt/im     (put everything in /opt/im sub-dir)

This keeps it separate and easy to clean up, especially if you want to
test or try multiple different packages.
