yes (i'll add the command to avoid confusion):
# cp /home/mattie/programs/cmake-2.8.4/Modules/FindOpenSSL.cmake
/usr/share/kde4/apps/cmake/modules/FindOpenSSL.cmake

ok, I downloaded the 2.6.4. when you invoke the right binary, it
automatically uses the associated cmake environment? so I ran:
~/programs/cmake-2.6.4-Linux-i386/bin/cmake ../telemeter-plasmoid

doesn't look good :/
for completeness I also tested with kde4.6.0/qt4.7.1, same problem

yes, of course ;)
