ENH: Implement linking with paths to library files instead of -L and -l separation. See bug #3832

Browse Source 
- 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.

Notes about linking on various platforms:
------------------------------------------------------------------------------
Linux, FreeBSD, Mac OS X, IRIX, Sun, Windows:
Linking to libraries using the full path works fine.
------------------------------------------------------------------------------
On AIX, more work is needed.
The "-bnoipath" option is needed. From "man ld":
Note: If you specify a shared object, or an archive file
containing a shared object, with an absolute or relative path
name, instead of with the -lName flag, the path name is
included in the import file ID string in the loader section of
the output file. You can override this behavior with the
-bnoipath option.
noipath
For shared objects listed on the command-line, rather than
specified with the -l flag, use a null path component when
listing the shared object in the loader section of the
output file. A null path component is always used for
shared objects specified with the -l flag. This option
does not affect the specification of a path component by
using a line beginning with #! in an import file. The
default is the ipath option.
This prevents the full path specified on the compile line from being
compiled directly into the binary.
By default the linker places -L paths in the embedded runtime path.
In order to implement CMake's RPATH interface correctly, we need the
-blibpath:Path option. From "man ld":
libpath:Path
Uses Path as the library path when writing the loader section
of the output file. Path is neither checked for validity nor
used when searching for libraries specified by the -l flag.
Path overrides any library paths generated when the -L flag is
used.
If you do not specify any -L flags, or if you specify the
nolibpath option, the default library path information is
written in the loader section of the output file. The default
library path information is the value of the LIBPATH
environment variable if it is defined, and /usr/lib:/lib,
otherwise.
We can pass -Wl,-blibpath:/usr/lib:/lib always to avoid the -L stuff
and not break when the user sets LIBPATH. Then if we want to add an
rpath we insert it into the option before /usr/lib.
------------------------------------------------------------------------------
On HP-UX, more work is needed. There are differences between
versions.
ld: 92453-07 linker linker ld B.10.33 990520
Linking with a full path works okay for static and shared libraries.
The linker seems to always put the full path to where the library
was found in the binary whether using a full path or -lfoo syntax.
Transitive link dependencies work just fine due to the full paths.
It has the "-l:libfoo.sl" option. The +nodefaultrpath is accepted
but not documented and does not seem to do anything. There is no
+forceload option.
ld: 92453-07 linker ld HP Itanium(R) B.12.41 IPF/IPF
Linking with a full path works okay for static libraries.
Linking with a full path works okay for shared libraries. However
dependent (transitive) libraries of those linked directly must be
either found with an rpath stored in the direct dependencies or
found in -L paths as if they were specified with "-l:libfoo.sl"
(really "-l:<soname>"). The search matches that of the dynamic
loader but only with -L paths. In other words, if we have an
executable that links to shared library bar which links to shared
library foo, the link line for the exe must contain
/dir/with/bar/libbar.sl -L/dir/with/foo
It does not matter whether the exe wants to link to foo directly or
whether /dir/with/foo/libfoo.sl is listed. The -L path must still
be present. It should match the runtime path computed for the
executable taking all directly and transitively linked libraries
into account.
The "+nodefaultrpath" option should be used to avoid getting -L
paths in the rpath unless we add our own rpath with +b. This means
that skip-build-rpath should use this option.
See documentation in "man ld", "man dld.so", and
http://docs.hp.com/en/B2355-90968/creatingandusinglibraries.htm
+[no]defaultrpath
+defaultrpath is the default. Include any paths that are
specified with -L in the embedded path, unless you specify the
+b option. If you use +b, only the path list specified by +b is
in the embedded path.
The +nodefaultrpath option removes all library paths that were
specified with the -L option from the embedded path. The linker
searches the library paths specified by the -L option at link
time. At run time, the only library paths searched are those
specified by the environment variables LD_LIBRARY_PATH and
SHLIB_PATH, library paths specified by the +b linker option, and
finally the default library paths.
+rpathfirst
This option will cause the paths specified in RPATH (embedded
path) to be used before the paths specified in LD_LIBRARY_PATH
or SHLIB_PATH, in searching for shared libraries. This changes
the default search order of LD_LIBRARY_PATH, SHLIB_PATH, and
RPATH (embedded path).

/** \class cmOrderLinkDirectories
* \brief Compute the best -L path order
*
* This class computes the best order for -L paths.
* It tries to make sure full path specified libraries are
* used. For example if you have /usr/mylib/libfoo.a on as
* a link library for a target, and you also have /usr/lib/libbar.a
* and you also have /usr/lib/libfoo.a, then you would
* want -L/usr/mylib -L/usr/lib to make sure the correct libfoo.a is
* found by the linker. The algorithm is as follows:
* - foreach library create a vector of directories it exists in.
* - foreach directory create a vector of directories that must come
* after it, put this in a map<dir, vector<dir>> mapping from a directory
* to the vector of directories that it must be before.
* - put all directories into a vector
* - sort the vector with a compare function CanBeBefore
* CanBeBefore returns true if a directory is OK to be before
* another directory. This is determined by looking at the
* map<dir vector<dir>> and seeing if d1 is in the vector for d2.
