This is useful on CentOS 7 whose "cmake" package provides cmake 2.8.12,
which is too old, but the "cmake3" package (from EPEL) provides version
3.6.3, which is satisfactory. Examples:
$ sh support/dependencies/check-host-cmake.sh 2.8 cmake cmake3
/usr/bin/cmake
$ sh support/dependencies/check-host-cmake.sh 3.1 cmake cmake3
/usr/bin/cmake3
$ sh support/dependencies/check-host-cmake.sh 3.8 cmake cmake3
(nothing)
