If the software uses autoconf, the --libdir parameter to the configure 
script will specify where shared libraries should be installed.

There's no real harm in placing libraries in /lib instead of /lib64, however 
you should not be doing this anyway.

You should always be installing software with rpm.  If the software doesn't 
have a specfile, write on yourself.  If you don't know how to write rpm 
specfiles, learn it.

Otherwise you:

• Maybe accidentally overwriting files installed by other packages

• Have nothing that would prevent an ordinary upgrade of other system 
packages removing critical files required by your manually-installed 
software, without notice.  rpm cannot track required dependencies by 
software that you did not install with rpm.

• Have nothing that would prevent an ordinary upgrade of other system 
packages from overwriting files that you've installed yourself, for the same 
reasons.
