# CMake configuration for BALL (http://www.ball-project.org)

# This file is - on purpose - heavily based on the CMake configuration
# of OpenMS (http://www.openms.de) to optimize synergy effects

PROJECT("BALL")

# TODO LIST:
#   BALL specific:
#
#   inherited from OpenMS:
#			- test for contrib headers (CONTRIB_HEADER_DIR ccmake variable - test one header for each required library)
#			- parallel build of test executables
#			- target to execute all EXAMPLES
