so dependencies can already ask for the new features

Adjust CMakeList to use add_dependency instead of FIND_PACKAGE for DeviceAccess library - now all path to headers are correctly added to the project when ControlSystemAdapter lib and DeviceAccess lib are installed in different directories.

If the hdf5 library is not available, the MicroDAQ module is automatically not build. You don't have to specify -DBUILD_MICRODAQ=OFF to make cmake run through.

 - Add missing required dependencies for boost
 - Remove deprecated header. Also not needed on xenial

use the new DeviceAccess .DUMMY_WRITEABLE variable in tests. Writing to the readonly version now throws.

remved the library without path from the _LIBRARIES. It is added with path by the config file anyway, which makes linking easiser because you don't need the link path variable.
