bash: Installation Names
10.4 Installation Names
=======================
By default, 'make install' will install into '/usr/local/bin',
'/usr/local/man', etc. You can specify an installation prefix other
than '/usr/local' by giving 'configure' the option '--prefix=PATH', or
by specifying a value for the 'DESTDIR' 'make' variable when running
'make install'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
give 'configure' the option '--exec-prefix=PATH', 'make install' will
use PATH as the prefix for installing programs and libraries.
Documentation and other data files will still use the regular prefix.
