I had a look at kdelibs/kjs/CMakeLists.txt, and actually the message tells you
You can build kjs without PCRE, but then you'll get a kjs, which will not work
for many websites.
If somebody does that, it will result in bug reports (which may be even hard
to recognize, since the user must find out whether his kjs has been built
with or without PCRE).
I suggest to make PCRE a hard requirement and not supporting the non-PCRE
