the buildsystem will now pick up and link all test cases according to the layer, e.g. backend tests will automatically be linked against the backend + library solely.

|
* Besides using existing MObject types (at the moment session::Clip),
|
|
* we create a yet-unknown new MObject subclass. When passing such to any
|
|
* BuilderTool subclass, the compiler enforces the definition of a catch-all
|
|
* function, which is called, when there is no other applicable \c treat(MO&)
|
|
* function. Note further, within the specific treat-functions we get direct
|
|
* references, without interfering with Placements and memory management.
|
|
* But from within the \c treat() function, we may access the wrapper object
|
|
* (i.e. shared_ptr, or lumiera::P or Placement) used when invoking the
|
|
* BuilderTool by using the protected interface on BuilderTool.
