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.

Clinton Stimpson 8576b3f978 OS X: Add support for @rpath in export files.
Also expand the IMPORTED_SONAME property for targets
to match the install_name.

Stephen Kelly af81a3c31b install(EXPORT): Ensure clean INTERFACE_INCLUDE_DIRECTORIES
Check that source and binary directories are not part of the
INTERFACE_INCLUDE_DIRECTORIES for installed IMPORTED targets.

This is limited to directories which do not contain generator
expressions to evaluate. Such paths can only be checked at time
of use of the imported target, which will be done in a follow up
patch.

Stephen Kelly 0b92602b81 Add the $<LINKED:...> generator expression.
This is both a short form of using a TARGET_DEFINED expression
together with a TARGET_PROPERTY definition, and a way to strip
non-target content from interface properties when exporting.

Stephen Kelly 94aeaf72c7 Split LINK_INTERFACE_LIBRARIES export handling into dedicated method. 2013-01-10 18:06:57 +01:00
Stephen Kelly a3aedb8152 Split the generator expression before extracting targets.
Now that we're processing a LINK_INTERFACE_LIBRARIES string, it
can contain targets. Make sure they are extracted for
namespacing purposes.

This needs to be restricted to strings which can actually have
targets named in them. For example, this is not done for
INTERFACE_COMPILE_DEFINITIONS, because even if there is a target
named 'foo', the string 'foo' in that property means that '-Dfoo'
will be set when compiling.

Stephen Kelly 0c657dc637 Add API to populate INTERFACE properties in exported targets.
The INTERFACE properties need to be preprocessed for context (build
location or install location) and to extract target names etc.

Stephen Kelly e04f737c7a Add API to extract target names from a genex string.
The TARGET_NAME expression, which requires a literal, provides
target names. $<TARGET_PROPERTY:tgt,prop> also provides target
names in the cases where tgt is a literal, so that TARGET_NAME is
not needed then in addition.

Stephen Kelly bf2ddceb4e Generate an early-return guard in target Export files.
Previously it was necessary for writers of Config files
which incude exported target files to write the guard themselves, but
this was not immediately obvious or documented. Options for them
would be to use a variable, or an INHERITED directory property in an
effort to avoid accidental name clashes in all contexts in
which find_package can be used.

Getting this right requires boiler plate code, so generate a simpler
check automatically instead.

Alex Neundorf 0cfd055acd exports: move the handling of missing targets into subclasses
Before, cmExportFileGenerator::ComplainAboutMissingTarget() was a virtual
function which had to be implemented in the subclasses. It is not
anymore. Instead, there is now a virtual function
HandleMissingTargets(), which is implemented in the two subclasses.
This makes e.g. dealing correctly with APPEND mode easier.

Alex Neundorf 8b5f448ba6 exports: first try at error handling if a target is missing
Now, if an imported target depends on a library which must come
from some other export set, cmake generates a check which errors
out if that target does not exist. I guess instead of completely
erroring out it would be better to only make the find_package() fail.

Alex Neundorf 87f4c01910 exports: accept a missing target if it is exported exactly once
If a target is exported, and a library it depends on is not part
of the same export set, before this patch cmake errored out.
With this patch, it now checks whether the missing target
is exported somewhere else exactly once, and accepts in this
case (because then it can determine the namespace for the
missing target and use this).

Alex Neundorf a2be068c75 install(EXPORT): Enforce existence of imported target files
Typical <package>Config.cmake files for find_package() rely only on the
files generated by install(EXPORT).  They might be wrong, for whatever
reasons, like people manually deleted files, projects were packaged
wrong by distributions, whatever.  To protect against this, add checks
that the file locations we are importing actually exist on disk.

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 06b0a692f4 ENH: Centralize default link interface computation
When LINK_INTERFACE_LIBRARIES is not set we use the link implementation
to implicitly define the link interface.  These changes centralize the
decision so that all linkable targets internally have a link interface.

Brad King 82fcaebe28 ENH: Pass dependent library search path to linker on some platforms.
- Move runtime path ordering out of cmComputeLinkInformation
    into its own class cmOrderRuntimeDirectories.
  - Create an instance of cmOrderRuntimeDirectories for runtime
    path ordering and another instance for dependent library
    path ordering.
  - Replace CMAKE_DEPENDENT_SHARED_LIBRARY_MODE with explicit
    CMAKE_LINK_DEPENDENT_LIBRARY_FILES boolean.
  - Create CMAKE_LINK_DEPENDENT_LIBRARY_DIRS boolean.
  - Create variables to specify -rpath-link flags:
      CMAKE_SHARED_LIBRARY_RPATH_LINK_<LANG>_FLAG
      CMAKE_EXECUTABLE_RPATH_LINK_<LANG>_FLAG
  - Enable -rpath-link flag on Linux and QNX.
  - Documentation and error message updates

Brad King 2cff26fa52 ENH: Support linking to shared libs with dependent libs
- Split IMPORTED_LINK_LIBRARIES into two parts:
      IMPORTED_LINK_INTERFACE_LIBRARIES
      IMPORTED_LINK_DEPENDENT_LIBRARIES
  - Add CMAKE_DEPENDENT_SHARED_LIBRARY_MODE to select behavior
  - Set mode to LINK for Darwin (fixes universal binary problem)
  - Update ExportImport test to account for changes

Brad King 7902bc06aa ENH: Implemented link-interface specification feature.
- Shared libs and executables with exports may now have
    explicit transitive link dependencies specified
  - Created LINK_INTERFACE_LIBRARIES and related properties
  - Exported targets get the interface libraries as their
    IMPORTED_LINK_LIBRARIES property.
  - The export() and install(EXPORT) commands now give
    an error when a linked target is not included since
    the user can change the interface libraries instead
    of adding the target.
