#
# GNUMakefile to build P4 API based applications on Linux and Windows.
#
# Usage:  make P4API=<p4dir>
#
# Common modifications:
#
#      P4API    - Set to path where you have extracted the p4api for
#                 the platform.
#
#      OS       - Currently this file supports Linux/g++ and Windows/.Net
#                 with a very simplistic use of "uname".  This may need
#                 some modifications depending on the operating system
#                 you are running.
#
#      CPP      - Modify for you compiler.  On windows you will need to
#                 add several directories to your PATH environment
#                 variable so the linker finds the correct libraries.
