# - This module creates a new 'lcov' target which generates
# a coverage analysis html output.
# LCOV is a graphical front-end for GCC's coverage testing tool gcov. Please see
# http://ltp.sourceforge.net/coverage/lcov.php
#
# Usage: you must add an option to your CMakeLists.txt to build your application
# with coverage support. Then you need to include this file to the lcov target.
#
# Example:
# IF(BUILD_WITH_COVERAGE)
# SET(CMAKE_C_FLAGS "-g -O0 -Wall -fprofile-arcs -ftest-coverage")
# SET(CMAKE_CXX_FLAGS "-g -O0 -Wall -fprofile-arcs -ftest-coverage")
# SET(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -fprofile-arcs -ftest-coverage -lgcov")
# include(${CMAKE_SOURCE_DIR}/cmake/lcov.cmake)
# ENDIF(BUILD_WITH_COVERAGE)
