In cmInstallTargetGenerator::GenerateScriptForConfig we were computing the full 'from' paths for all target files to be installed, but only computing a 'to' path for the "main" target file. This commit teaches the method to compute both 'from' and 'to' paths for every target file to be installed. The result is cleaner, easier to follow, and will allow installation tweaks to be added later on all target files.
