Stephen Kelly d70204a86a Only output includes once after the start of 'generate-time' when debugging.
During configure-time, GetIncludeDirectories may be called too, for example
if using the export() command. As the content can be different, it should
be output each time then.

Stephen Kelly bd82bb4787 Clear the link information in ClearLinkMaps.
The cache here needs to be cleared if GetLinkInformation is called
at configure-time, such as during an export().

The next commit does exactly that, and without this patch,
the LinkLanguage test would fail.

Stephen Kelly e98799105b Make INTERFACE determined properties readable in generator expressions.

Stephen Kelly d7f1520938 Don't wrap all targets in LINK_LIBRARIES in a TARGET_NAME genex.
It is not necessary and the current state is unintentional. Before
this patch,

 target_link_libraries(foo bar)

causes the LINK_LIBRARIES property of foo to contain

 $<TARGET_NAME:bar>

instead of just

 bar

Stephen Kelly 7171fd0a90 Add a way to check INTERFACE user property compatibility. 2013-01-15 14:33:45 -05:00
Stephen Kelly 1da75022bb Don't include generator expressions in old-style link handling.
Don't add generator expressions to variables which are used
for CMP0003, CMP0004, and the old-style _LIB_DEPENDS content. They
will not be evaluated when read anyway and would probably confuse
the code reading them.

This makes it legitimate to use target_link_libraries with generator
expressions as arguments.
2013-01-13 09:59:42 +01:00
Stephen Kelly 77d2646784 Allow generator expressions in LINK_INTERFACE_LIBRARIES.
The Config and IMPORTED_ variants may also contain generator
expressions.

If 'the implementation is the interface', then the result of
evaluating the expressions at generate time is used to populate
the IMPORTED_LINK_INTERFACE_LIBRARIES property.

1) In the case of non-static libraries, this is fine because the
  user still has the option to populate the LINK_INTERFACE_LIBRARIES
  with generator expressions if that is what is wanted.

2) In the case of static libraries, this prevents a footgun,
  enforcing that the interface and the implementation are really
  the same.

  Otherwise, the LINK_LIBRARIES could contain a generator
  expression which is evaluated with a different context at build
  time, and when used as an imported target. That would mean that the
  result of evaluating the INTERFACE_LINK_LIBRARIES property for
  a static library would not necessarily be the 'link implementation'.

  For example:

    add_library(libone STATIC libone.cpp)
    add_library(libtwo STATIC libtwo.cpp)
    add_library(libthree STATIC libthree.cpp)

    target_link_libraries(libtwo
      $<$<STREQUAL:$<TARGET_PROPERTY:TYPE>,STATIC_LIBRARY>:libone>)
    target_link_libraries(libthree libtwo)

  If the LINK_LIBRARIES content was simply copied to the
  IMPORTED_LINK_INTERFACE_LIBRARIES, then libthree links to libone, but
  executables linking to libthree will not link to libone.

3) As the 'implementation is the interface' concept is to be
  deprecated in the future anyway, this should be fine.

Stephen Kelly 3581b96caa Process the INTERFACE_PIC property from linked dependencies
This allows a dependee to inform a target that it should have its
POSITION_INDEPENDENT_CODE property set to ON, or OFF. The value of
the POSITION_INDEPENDENT_CODE property, if set, must be consistent
with any INTERFACE_POSITION_INDEPENDENT_CODE properties on dependees.

Add a test covering the consistency checks on platforms where they run.
2013-01-10 09:54:52 -05:00
Stephen Kelly 042ecf0471 Add API to calculate link-interface-dependent bool properties or error.
This new method checks that the property FOO on a target is consistent
with the INTERFACE_FOO properties of its dependees. If they are not the
consistent, an error is reported. 'Consistent' means that iff the
property is set, it must have the same boolean value as all other
related properties.

Stephen Kelly bf5ece51c3 Keep track of properties used to determine linker libraries.
Those properties can't later be implicitly defined by the interface
of those link libraries.

Stephen Kelly 7653862798 Add LINK_LIBRARIES property for direct target link dependencies
Previously we kept direct link dependencies in OriginalLinkLibraries.
The property exposes the information in the CMake language through the
get/set_property commands.  We preserve the OriginalLinkLibraries value
internally to support old APIs like that for CMP0003's OLD behavior, but
the property is now authoritative.  This follows up from commit d5cf644a
(Split link information processing into two steps, 2012-11-01).

This will be used later to populate the link interface properties when
exporting targets, and will later allow use of generator expressions
when linking to libraries with target_link_libraries.

Also make targets depend on the (config-specific) union of dependencies.
CMake now allows linking to dependencies or not depending on the config.
However, generated build systems are not all capable of processing
config-specific dependencies, so the targets depend on the union of
dependencies for all configs.
2013-01-08 09:02:43 -05:00
Stephen Kelly 40cf3fb95b Make linking APIs aware of 'head' target
The 'head' is the dependent target to be linked with the current target.
It will be used to evaluate generator expressions with proper handling
of mapped configurations and is used as the source target of properties.

This requires that memoization is done with a key of a pair of target
and config, instead of just config, because now the result also depends
on the target.  Removing the memoization entirely is not an option
because it slows cmake down considerably.

Stephen Kelly 894f52f32d Handle INTERFACE properties transitively for includes and defines.
Contextually, the behavior is as if the properties content from another
target is included in the string and then the result is evaluated.

Stephen Kelly 0bbae6f95f Revert "Move GetLinkInformation to cmGeneratorTarget"
As we can't move all linking related code from cmTarget, it makes
sense to reverse the move in some cases.

The ComputePDBOutputDir added by commit 3f60dbf1 (Add
PDB_OUTPUT_DIRECTORY and PDB_NAME target properties, 2012-09-25) falls
back to the current binary directory instead of the target output
directory as before.  When no PDB_OUTPUT_DIRECTORY property is set we
instead should fall back to the target output directory where .pdb files
used to go before the new property was added.
