CMake highlighting not works for KDE related keywords
KDE has some special CMake commands like kde4_add_executable and these not recognized by pygments in Sphinx.
I don't know if this is the right solution but when I changed following line:
(r'\b([A-Za-z_]+)([ \t]*)(\()', bygroups(Name.Builtin, Text,
with this one:
(r'\b([A-Za-z0-9_]+)([ \t]*)(\()', bygroups(Name.Builtin, Text,
everything started to work properly
