Stephen Kelly 7a3e45b9d4 Export: Prefix relative items with genexes in INSTALL_INTERFACE.
Code such as

 target_include_directories(foo INTERFACE
   $<INSTALL_INTERFACE:include$<FOO>>
 )

should be treated as a relative directory, despite the genex, after
the INSTALL_INTERFACE is stripped away.

Previously, this would generate a relative directory on export, which
would be an error on import, so no policy is needed.

Stephen Kelly f088a32450 Export: Process INSTALL_INTERFACE in INCLUDES DESTINATION.
Code such as

 install(TARGETS ...
   INCLUDES DESTINATION $<INSTALL_INTERFACE:include>
 )

should behave as if the INSTALL_INTERFACE wrapper were not present.

Stephen Kelly 9eedc850eb Export: Process relative includes after genex evaluation.
In code such as

 install(TARGETS ...
   INCLUDES DESTINATION $<FOO>include
 )

the generator expressions are evaluated at generate-time. Delay
determining whether each entry is a relative path until after
the generator expressions are evaluated. Such relative paths
are based relative to the CMAKE_INSTALL_PREFIX.

Stephen Kelly f063c45589 Consider targets with double colons to be IMPORTED or ALIAS targets.
Introduce a policy to control the behavior.

The AliasTargets unit test already tests that using a
double-semicolon in the name is not an error. Change the ExportImport
test to use a namespace with a double-semicolon too.

Introduce a target property to control this behavior variable
to set the default value for the target property.

This does not affect try_compile runs.

These paths can be prepended with the ${_IMPORT_PREFIX} generated

Stephen Kelly 650e61f833 Add a convenient way to add the includes install dir to the INTERFACE.
Export the INCLUDES DESTINATION without appending to the
INTERFACE_INCLUDE_DIRECTORIES of the target itself. That way, a target
can be exported multiple times with different INCLUDES DESTINATION
without unintended cross-pollution of export sets.

Stephen Kelly 574fec97fd Export: Generate INTERFACE_LINK_LIBRARIES property on targets.
This property is generated only for targets which have recorded
policy CMP0022 as NEW, and a compatibility mode is added to
additionally export the old interfaces in that case too.

If the old interfaces are not exported, the generated export files
require CMake 2.8.12. Because the unit tests use a version which
is not yet called 2.8.12, temporarily require a lower version.

Stephen Kelly 4f7ceb56d1 Test non-IMPORTED libraries in the INTERFACE of IMPORTED libraries.
If a non-IMPORTED library is added to the INTERFACE_LINK_LIBRARIES
of a IMPORTED target, the non-IMPORTED target needs to become a
target dependency and link dependency of the consuming target.

This is already the case since commit 30962029 (Make targets depend
on the link interface of their dependees, 2012-12-26), and fixed in
the parent commit, so test that it works.

Stephen Kelly b5d6f5dd5b Add EXPORT_NAME property.
This allows for example, the buildsystem to use names like 'boost_any'
instead of the overly generic 'any', and still be able to generate
IMPORTED targets called 'boost::any'.

Stephen Kelly 236133e79e Handle targets in the LINK_LIBRARIES of try_compile.
Imported targets are re-exported so that they can be used by the
try_compile generated code with target_link_libraries.

This makes the use of the cmake_expand_imported_targets macro
obsolete. The macro is not able to expand the generator expressions
which may appear in the IMPORTED_LINK_INTERFACE_LIBRARIES content.
Instead it just sees them as 'not a target'.

Stephen Kelly 79ae968a18 Revert "Add a way to exclude INTERFACE properties from exported targets."
This reverts commit 2c3654c3de.

The removal of some tests added in commit 77cecb77 (Add includes and compile
definitions with target_link_libraries., 2012-11-05) are also squashed
into this commit.
2013-02-13 15:12:31 +01:00
Stephen Kelly 77cecb778f Add includes and compile definitions with target_link_libraries.
This establishes that linking is used to propagate usage-requirements
between targets in CMake code. The use of the target_link_libraries
command as the API for this is chosen because introducing a new command
would introduce confusion due to multiple commands which differ only in
a subtle way.

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 93034a8350 Fix linking to imported libraries test.

Stephen Kelly 894f52f32d Handle INTERFACE properties transitively for includes and defines.
Contextually, the behavior is as if the properties content from another

particular configuration.  Adapt the implementation from KDE's
HANDLE_IMPORTED_TARGETS_IN_CMAKE_REQUIRED_LIBRARIES which has been in
