No we don't. Both are unsupported in Qt4/KDE4 (the latter may actually
just be deprecated still, though that was already the case in KDE3). Its
KDEDIRS and the purpose is not for building KDE stuff, but for running
apps that are not installed in the same prefix.

I've recently got a private mail with some fixes for the FindBoost.cmake
thats (hopefully) getting into a CMake 2.6.x release. I just need to get
around at backporting some of them to the kdevplatform one (because the
2.6 version uses 2.6 features)
