As far as I understand, the CMakeLists do not have a variable that contain
"libelogind", and we can’t change the LIBSYSTEMD variable content because it
is used in other places (notably to find headers, where “libelogind” would not
work).

So we have to ignore the CMakeLists entirely and bypass the .in substitution.
