# WARNING: Only linux is currently supported by this cmake build file.

# This file is used to build cataclysm with CMake.
#
# To use it, install cmake, then:
#
# cd cataclysm
# mkdir build
# cd build
# cmake -G "Unix Makefiles" -DLOCALIZE=ON -DSDL=OFF ..
# make
#
# This will build and install cataclysm into the build directory.
#
# "Unix Makefiles" is a generator, you can get a list of supported generators
# on your system by running "cmake" without any arguments.

# -DOPTION_NAME=ON/OFF enables/disables OPTION_NAME

OPTION(SOUND "Use SDL mixer to play music and sounds." ON)

# Note: The CMake documentation says it's better to list the actual source
#       files here, as otherwise cmake won't know to rerun when a new file
#       is added. However, currently the Makefile also just scans for source
#       files, so this approach should be "good enough".
