Create cmake/cpack/find/nabla.cmake & cmake/cpack/find/compoment/template.cmake, script component install rules has been added creating interface install variables in separate files which can be used with find_package. TODO: global configuration Nabla file including the component files if found in package, makes flexible search requests for package parts
