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.

Brad King 5594ad4885 ENH: Updated exporting and importing of targets to support libraries and configurations.
- Created cmExportFileGenerator hierarchy to implement export file generation
  - Installed exports use per-config import files loaded by a central one.
  - Include soname of shared libraries in import information
  - Renamed PREFIX to NAMESPACE in INSTALL(EXPORT) and EXPORT() commands
  - Move addition of CMAKE_INSTALL_PREFIX to destinations to install generators
  - Import files compute the installation prefix relative to their location when loaded
  - Add mapping of importer configurations to importee configurations
  - Rename IMPORT targets to IMPORTED targets to distinguish from windows import libraries
  - Scope IMPORTED targets within directories to isolate them
  - Place all properties created by import files in the IMPORTED namespace
  - Document INSTALL(EXPORT) and EXPORT() commands.
  - Document IMPORTED signature of add_executable and add_library
  - Enable finding of imported targets in cmComputeLinkDepends
