Further reading of the CMake output (at the end) does not say that they 
were found and does not say that they were not found.  Nice :-(

  IAC, you are saying that the problem is the wording of the message 
(">=" is missing) and in fact they are found correctly.

And yes, reading the CMakeCache.txt file does indicate that they were found.

Still, as I said, there is no problem building KDE-4.4.  But, I can 
install 4.2 but that doesn't solve the two mysteries: (1) why does 
KDE-4.4 build with no error; (2) why is KDE still using the old version.

And, as I am sure you know, KDE used to have a web page that listed the 
dependencies but it was taken down.  IMHO, there is no excuse for not 
having it.  The replacement for this was a page on TechBase suggesting 
that you use the packages from your distro, but not stating which 
versions were required.  So, now the only information on which apps and 
which versions are required is this TechBase page:

http://techbase.kde.org/Getting_Started/Build/KDE4/LFS

And it appears that the author (I) of the page has no resources with 
which to find the information other than trial and error; it is this 
trial and error that results in the struggles.  How do the Gentoo people 
find this stuff out.  Do the developers refuse to help them as well, or 
do they cooperate?
