I think thirdparty build few things with cmake - main problem older distros
have old cmake and new projects sometimes actually use new cmake features
(and you probably do not want to build your own cmake - because it installs
few modules for searching system-wide installed software... or at least my
navie understanding of cmake tells me this - can be wrong!)
