# Main CMake file for the ZoneMinder project.
# Created by mastertheknife (Kfir Itzhak)
# The goal is to ease up the installation of zoneminder.
# Our current installation method (using autotools) is outdated, slow and breaks now and then.
# The CMake installation method will require no parameters at all, default should sufficient and reliable.
# It will be still possible to install ZoneMinder using autotools, they don't conflict with each other. The cmake way is a complete re-write (different syntax) and aims to be identical to the autotools way,
# by having options using the same name and leaving ZM totally unmodified, while providing exactly the same things that ZM expects (config.h, configuration in *.in files, etc).
#
# For more information and installation, see the INSTALL file
