# CheckCSourceRuns
# ----------------
#
# Check if the given C source code compiles and runs.
#
# CHECK_C_SOURCE_RUNS(<code> <var>)
#
# ::
#
# <code> - source code to try to compile
# <var> - variable to store the result
# (1 for success, empty for failure)
# Will be created as an internal cache variable.
#
# The following variables may be set before calling this macro to modify
# the way the check is run:
#
# ::
#
# CMAKE_REQUIRED_FLAGS = string of compile command line flags
# CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
# CMAKE_REQUIRED_INCLUDES = list of include directories
# CMAKE_REQUIRED_LIBRARIES = list of libraries to link
# CMAKE_REQUIRED_QUIET = execute quietly without messages
