############ USAGE ############

# ./RunCPPv5.bash dev = compile with all compiler warnings
# ./RunCPPv5.bash deb = compile with support for debuggers and profilers (gprof, gdb, valgrind, etc.)
# ./RunCPPv5.bash rel = compile for best performance
# ./RunCPPv5.bash     = standart compilation

# "rec" can be added to recompile even without any detected changes
