ENH: Implement linking with paths to library files instead of -L and -l separation. See bug #3832
- This is purely an implementation improvement. No interface has changed.
- Create cmComputeLinkInformation class
- Move and re-implement logic from:
cmLocalGenerator::ComputeLinkInformation
cmOrderLinkDirectories
- Link libraries to targets with their full path (if it is known)
- Dirs specified with link_directories command still added with -L
- Make link type specific to library names without paths
(name libfoo.a without path becomes -Wl,-Bstatic -lfoo)
- Make directory ordering specific to a runtime path computation feature
(look for conflicting SONAMEs instead of library names)
- Implement proper rpath support on HP-UX and AIX.
