Not really something to do with kdevelop, but KDE's cmake code sets up
a variable to use with add_definitions() to enable exceptions for a
given directory: KDE4_ENABLE_EXCEPTIONS. So you can just do this:

add_definitions(${KDE4_ENABLE_EXCEPTIONS})

to enable exception support. I'm not sure why adding to cmake-cxx-flags
doesn't work, but I do recall that FindKDE4Internal.cmake does some
nasty things wrt. compiler flags that don't end up in the cache and are
hence being re-run on each cmake run.
