build: Install to system's path (prefixed by destdir)

This change is useful for debian packaging

Runtime destination rely on RUNTIME_OUTPUT_DIRECTORY property

This was introduced first in #1134 and then droped in #1848

This will be helpful for packaging,
or example on Tizen install using RPM macro: "%make_install"
of Debian's debhelper.

Work along CMAKE_INSTALL_PREFIX,
or/and can be overloaded individualy to alternate locations.

Email has been updated for community support.
