+# - Check if a C function can be linked
+# CHECK_FUNCTION_EXISTS(<function> <variable>)
+#
+# Check that the <function> is provided by libraries on the system and
+# store the result in a <variable>.  This does not verify that any
+# system header file declares the function, only that it can be found
+# at link time (considure using CheckSymbolExists).
+#
+# 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
