-# - Check if a symbol exists as a function, variable, or macro
-# CHECK_SYMBOL_EXISTS(<symbol> <files> <variable>)
-#
-# Check that the <symbol> is available after including given header
-# <files> and store the result in a <variable>.  Specify the list
-# of files in one argument as a semicolon-separated list.
-#
-# If the header files define the symbol as a macro it is considered
-# available and assumed to work.  If the header files declare the
-# symbol as a function or variable then the symbol must also be
-# available for linking.  If the symbol is a type or enum value
-# it will not be recognized (consider using CheckTypeSize or
-# CheckCSourceCompiles).
-#
-# 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
