# Try to locate the software as named in argument.
# This is a sequential search of all possible locations of the software.
# Usage: locate_sw <SW-Name>
# It prints a string showing the paths leading to the include, lib and bin
# directory of the software, separated by colons.  E.g., if the software is
# located in /usr/sdt/*, it prints
# /usr/sdt/include:/usr/sdt/lib:/usr/sdt/bin
# Any component that is not found will be returned as an empty string. E.g.,
# if somehow the header files of the software are not found, it prints
# :/usr/sdt/lib;/usr/sdt/bin

# Function definitions
