[CMake] CPack: Ignoring files using regex

[Glenn Coombs]

The regexp you're using matches anything where the last character at the
end of the line isn't one of the characters inside the square brackets.  I
don't think cmake's regexps allow negation of words so specifying a regexp
that matches everything except projectA/, README and CMakelists.txt is
going to be tricky.

You could just list the known items that you do want to ignore.  Something
like this:

set(CPACK_SOURCE_IGNORE_FILES "/build/;/extrafiles/;/temp/")

will hopefully ignore directories called build, extrafiles and temp.  It
isn't exactly what you want but might help.
