When using this tool, the wscript will look like:
def options(opt):
opt.load('compiler_cxx cryptopp')
def configure(conf):
conf.load('compiler_cxx cryptopp')
conf.check_cryptopp()
def build(bld):
bld(source='main.cpp', target='app', use='CRYPTOPP')
Options are generated, in order to specify the location of cryptopp includes/libraries.
