Do not install 3rd-party dependencies by default

Disable the CMake_INSTALL_DEPENDENCIES option by default and turn it on
explicitly in our packaging scripts.  This simplifies packaging in
distributions that provide the dependencies for us without having to
install them.  We only need 3rd-party runtime dependencies to be
installed for packaging with redistributable binaries.
