To manage the lifetime of `cmTargetInternals`, the private implementation of
`cmTarget`, use `std::unique_ptr<cmTargetInternals>` instead of
`cmTargetInternalPointer`, which is removed.
`cmTarget` is made non-copyable but movable.
The new optional `before` parameter in `cmTarget::AddSource` and
`cmGeneratorTarget::AddSource` allows to prepend a source file
to the sources list instead of appending it.
These new capabilities enable to manage link directories
Two new properties:
* target properties: LINK_DIRECTORIES and INTERFACE_LINK_DIRECTORIES
One new command
* target_link_directories(): to populate target properties
Fixes: #17215
Previously the command did not allow naming targets on the LHS that
were not created in the calling directory. Lift this restriction to
enable more flexible use by projects.
Targets named on the RHS will need to be looked up during generation in
the scope of the call site rather than the scope of the LHS target.
Introduce an internal syntax in `[INTERFACE_]LINK_LIBRARIES` properties
to specify target names that need to be looked up in a directory other
than that containing the target on which the property is set. Add
minimal documentation of the syntax to help users that encounter it.
Unfortunately CMake previously did allow such calls in the case that
only `INTERFACE` libraries are specified, but those libraries would be
looked up in the target's directory rather than the caller's. Add
policy `CMP0079` to enable the new behavior with new lookup scope in a
compatible way.
Fixes: #17943
This family enable to manage link flags
Three new properties:
* directory property: LINK_OPTIONS
* target properties: LINK_OPTIONS and INTERFACE_LINK_OPTIONS
Two new commands
* add_link_options(): to populate directory property
* target_link_options(): to populate target properties
Fixes: #16543
Run the `clang-format.bash` script to update all our C and C++ code to a
new style defined by `.clang-format`. Use `clang-format` version 6.0.

Some generators auto-generate targets. For example VS generators create
the ALL_BUILD target. Add the ability to mark targets as generator
provided and return that info through cmake-server codemodel.

Add an `IMPORTED_LIBNAME[_<CONFIG>]` target property to specify a library
name to be placed on the link line in place of an interface library
since it has no library file of its own. Restrict use of the property
to imported `INTERFACE` libraries.
This will be particularly useful for find modules that need to provide
imported libraries from system SDKs where the full path to the library
file is not known. Now such find modules will be able to provide an
imported interface library and set `IMPORTED_LIBNAME` to refer to the
SDK library by name.
Issue: #15267
The GetProperty method is now just accessing contained data, meaning it
can be implemented in cmState.
Remove the cmMakefile context from the signature as a result and remove
the overload with the same signature.
Add a GetComputedProperty to cmTarget so that templates can be properly
instantiated. Otherwise the Commands would need to be able to reach the
specializations which are currently in cmTarget.cxx.
As a side-effect, the CMP0026 warning now gives a backtrace to the
target when issued from a generator expression.
