Unless you are building an O/S packaging system package (eg .deb or .rpm), you 
should *not* install locally build software with the /usr prefix.

No.  To use your locally built Qt 5.x, you will need to make sure 
/usr/local/<whatever> is known to your build environment (path, compiler, 
linker, etc.).  (Generally, this should normally be set up by default, but it 
can't hurt to check.)
