ENH: First step of install script generator cleanup. Each configuration to be installed is now separately handled instead of using variables to store per-configuration names. For targets the component and configuration install-time tests are now done in the install script instead of in the FILE(INSTALL) command. This cleans things up like not trying to strip a file that was optionally not installed. It also simplifies the code for install_name adjustment on OSX.
