CMake induced Problems
**********************

It is not possible to add dependencies to the CMake generated INSTALL target
============================================================================

This prevents us from using cmake's :code:`install()` command in combination
with custom targets because we can not ensure that the custom target is build
before the :code:`install` target. As a workaround we have to implement additional
custom-targets for the installation operations.

CMake does not support lists that have only one empty element
=============================================================

Because lists are implemented as ; separated strings and the notation
does not have the list end with a ;, it is not possible to have a list
with one empty element. This especially is a problem in algorithms which handle
lists. Our function :code:`cpf_append_list()` is used to detect this problem,
but when it occurs, there is no general solution to it.
