It just turned out that the problem was not the above, in particular since
I require version 2.8 which sets CMP0005 to NEW. Hence cmake takes care of
proper quoting itself.

The problem was rather an earlier add_definitions line which tried to set a
define that included a semicolon. Apparently that is something that make
cmake create completely bogus CXX_DEFINES lines in the flags.make file.
I've reported a bug about that now.
