also export the LIBRARY_DIRS variable to the calling CMakeLists.txt (needed to publish it to further downstream dependencies)

Fixed the confusing and inconsistently used names *_LINK_FLAGS and *_LINKER_FLAGS by always setting and getting both variables

- set required version for the ControlSystemAdapter

added TINE_EXPORT C macro/constant to the compiler flags, which seens to be required for the latest DOOCS version

replace any additional slashes in the DOOCS property name by a dot, since DOOCS does not support additional slashes in the names.

run ApplicatioBase::initialise() in eq_create() and ApplicationBase::run() in eq_init_epilogue(), so the application is only started when all variables are properly initialised.

Added a eq_create function to initialise applications based on the ApplicationBase class. The macros BEGIN_DOOCS_SERVER/END_DOOCS_SERVER are now deprecated.

Unified cs awith da

removed all uses of the ProcessScalar class and replaced it with the ProcessArray (ProcessScalar will be removed from the CSA soon)

moved to the "ProcessVariableAccessors" branch of the control system adapter, which unifies the interface with DeviceAccess

Added new `dapi` component in FindDOOCS.cmake module.

need to find DOOCS_DIR first, since this is the variable which might be specified at the cmake command line
