# Try to capture the initial set of cmake command line args passed by
# the user for configuration.
# Original Recipe taken from http://stackoverflow.com/questions/10205986/how-to-capture-cmake-command-line-arguments
# and adapted in ROOT and GeantV
#
# Note: The entries will live on CMakeCache.txt, so re-configuring with
# a command line that doesn't include an option won't remove it. You need
# to remove the CMakeCache.txt file, or override the value via the command line.
#
# The original cmake command is recorded as:
# recmake_initial.sh
# The history of tweaks to the configuration (except those from ccmake) is
# recorded as:
# recmake_replay.sh
