Stephen Kelly 48a4cf2182 Revert "Allow target_link_libraries with IMPORTED targets."
This reverts commit 9cfe4f1b76.

It turns out that correctly adding the content to
the IMPORTED_LINK_INTERFACE_LIBARIES_<CONFIG> of an upstream target
from the buildsystem of a downstream project is not simple.

If upstream had added the INTERFACE content, the config-specific
properties would  be determined by the DEBUG_CONFIGURATIONS of
upstream.

As downstream, we don't have any information about what
the DEBUG_CONFIGURATIONS of upstream were, so we can't determine
which configuration-specific properties to populate. The best we can do
is add it to all of them or add it to the ones downstream considers to
be DEBUG_CONFIGURATIONS, neither of which is a good solution.

So, removing the porcelain API for that is the best approach. A human
can still determine which properties to populate and use
the set_property API to populate the desired properies.

Another solution to this would be for upstream targets to publish
what they consider DEBUG_CONFIGURATIONS, but that can be added in
a future release.

Stephen Kelly 9cfe4f1b76 Allow target_link_libraries with IMPORTED targets.
This makes it possible to use:

 target_link_libraries(foo LINK_INTERFACE_LIBRARIES bar)

where foo is an IMPORTED target. Other tll() signatures are not
allowed.

Brad King b87d7a60a0 Add OBJECT_LIBRARY target type
This library type can compile sources to object files but does not link
or archive them.  It will be useful to reference from executable and
normal library targets for direct inclusion of object files in them.

Diagnose and reject the following as errors:

* An OBJECT library may not be referenced in target_link_libraries.

* An OBJECT library may contain only compiling sources and supporting
  headers and custom commands.  Other source types that are not normally
  ignored are not allowed.

* An OBJECT library may not have PRE_BUILD, PRE_LINK, or POST_BUILD
  commands.

* An OBJECT library may not be installed, exported, or imported.

Some of these cases may be supported in the future but are not for now.

Teach the VS generator that OBJECT_LIBRARY targets are "linkable" just
like STATIC_LIBRARY targets for the LinkLibraryDependencies behavior.

Brad King b1f12f8042 target_link_libraries: Simplify argument processing state tests
Remove extra parens in test for not handling LINK_INTERFACE_LIBRARIES.
Remove redundant test for equality with ProcessingPrivateInterface
subsumed by test for inequality with ProcessingPublicInterface.

Makes it possible to specify the link dependencies and link
interfaces in one command without repetition.

Alex Neundorf 6acc71c09d New CMP0016 for deciding whether an unknown target in TLL() is an error.
When set to OLD, target_link_libraries() silently accepts if it is called
with only one argument and this one argument is not a target.
When set to NEW, this is an error. By default it is a warning now.

Alex Neundorf 6aef6d84d7 Just warn in case of a bad target as only argument for t_l_l()
As discussed on cmake-devel, if target_link_libraries() is called with
only one argument, and this one argument is not a valid target, just
print a warning but don't fail, since otherwise probably some existing
code somewhere might stop building.

Alex Neundorf c786635149 Make target_link_libraries() complain if bad target name is used
target_link_libraries() did not complain if there was only one argument,
and this one (first) argument wasn't a valid target name, e.g.

add_executable(hello main.cpp)
target_link_libraries(-static-intel)

Here the target "hello" was forgotten in the tll() call, but cmake didn't
complain. With this commit it does.

Brad King 96afb12087 Convert CMake to OSI-approved BSD License
This converts the CMake license to a pure 3-clause OSI-approved BSD
License.  We drop the previous license clause requiring modified
versions to be plainly marked.  We also update the CMake copyright to
cover the full development time range.

Brad King 3c5cf1bb8c ENH: Allow a custom list of debug configurations
Create a DEBUG_CONFIGURATIONS global property as a way for projects to
specify which configuration names are considered to be 'debug'
configurations.

Brad King 94c1fe83fd ENH: Make link interface mode more distinct
Rename the recently added INTERFACE mode of the target_link_libraries()
command to LINK_INTERFACE_LIBRARIES.  This makes it much more distinct
from a normal call to the command, and clearly states its connection to
the property of the same name.  Also require the option to appear
immediately after the target name to make it a mode rather than an
option.

Brad King e322d288af ENH: Simple specification of link interfaces
Create an INTERFACE option to the target_link_libraries command to help
set the LINK_INTERFACE_LIBRARIES and LINK_INTERFACE_LIBRARIES_DEBUG
properties.  This will help users specify link interfaces using
variables from Find*.cmake modules that include the 'debug' and
'optimized' keywords.

Brad King 40fc9174e2 ENH: Tolerate repeated link library types
The "debug", "optimized", and "general" link library type specifier
arguments to the target_link_library commands are sometimes repeated in
user code due to variable expansion and other complications.  Instead of
silently accepting the duplicates and trying to link to a bogus library
like "optimized.lib", warn and ignore the earlier specifiers.

Brad King 22c62c9e65 BUG: Sweeping changes to cleanup computation of target names. This should
fix many bugs related to target names being computed inconsistently.

- Centralized computation of a target's file name to a method in
  cmTarget.  Now that global knowledge is always available the
  *_CMAKE_PATH cache variables are no longer needed.

- Centralized computation of link library command lines and link
  directory search order.

- Moved computation of link directories needed to link CMake targets
  to be after evaluation of linking dependencies.

This also removed alot of duplicate code in which each version had its
own bugs.

This commit is surrounded by the tags

  CMake-TargetNameCentralization1-pre

and

  CMake-TargetNameCentralization1-post

so make the large set of changes easy to identify.
