# This CMake definition supports several -D command line options:
#
# -DDEV_PKG=1 Development package configuration
# -DBUILD_DOC=1 Man pages generated
# -DIGNORE_LIBDIR=1 Installation of rmr libries is into /usr/local/lib and ignores
# value in CMAKE_INSTALL_LIBDIR.
# system preferred (typically /usr/local/lib64).
# -DPRESERVE_PTYPE=1 Do not change the processor type when naming deb packages
# -DPACK_EXTERNALS=1 Include external libraries used to build in the run-time package
# (This makes some stand-alone unit testing of bindings possible, it
# is not meant to be used for production package generation.)
# -DSKIP_EXTERNALS=1 Do not use NNG submodule when building; uee installed packages
# -DMAN_PREFIX=<path> Supply a path where man pages are installed (default: /usr/share/man)
