# - Run cppcheck on c++ source files as a custom target and a test
#
# include(CppcheckTargets)
# add_cppcheck(<target-name> [UNUSED_FUNCTIONS] [STYLE] [POSSIBLE_ERROR] [FAIL_ON_WARNINGS]) -
# Create a target to check a target's sources with cppcheck and the indicated options
# add_cppcheck_sources(<target-name> [UNUSED_FUNCTIONS] [STYLE] [POSSIBLE_ERROR] [FAIL_ON_WARNINGS]) -
# Create a target to check standalone sources with cppcheck and the indicated options
#
# Requires these CMake modules:
# Findcppcheck
#
# Requires CMake 2.6 or newer (uses the 'function' command)
