Things that are compiled from source are usually put in /usr/local ,
because your distro's package manager will leave that directory and its
subdirectories alone. /opt is usually for binary packages like Android
Studio or Orrible.

What? Everything that's built with autotools (which is almost every
project that's larger than a toy) has the --prefix= option. This
defaults to /usr/local/ but you can set it to anything you like. You'd
set it to /usr/ to install the stuff alongside all the system packages.
Well-behaved packages put their binaries in $PREFIX/bin , libraries in
$PREFIX/lib , documentation in $PREFIX/share/doc , etcetera.

If your program depends on libraries, and those libraries are installed
in a non-standard place, you may need to add that place to
/etc/ld.so.conf and rerun ldconfig before the program will run.
