# This module looks for an installed LCOV environment, and sets some paths for the executables
#
# see:
#  http://ltp.sourceforge.net/coverage/lcov.php

# It will set the following variables:
#
#  LCOV_FOUND
#  LCOV_EXECUTABLE
#  LCOV_GENHTML_EXECUTABLE
#

    lcov
    DOC "Path to `lcov` binary"

    genhtml
    DOC "Path to LCOV `genhtml` binary"
