Now CTL uses cmake to configure builds.
Everything in the repository is now build with a few simple commands.
e.g. a typical build from CTL root directory would look like:
    mkdir build && cd build
    cmake ..
    make check
    make
    sudo make install
fix output of file ext.
fix cmake when nuke not installed
install IlmImfCtl to correct location
clean up typos in usage text
