Summary0011249: FindFLEX.cmake: Sends a CMake fatal error if flex execution fails or doesn't support --version flag
DescriptionAs reported by Bill Hoffman:

In FindFLEX.cmake, you have this:
 EXECUTE_PROCESS(COMMAND ${FLEX_EXECUTABLE} --version
   OUTPUT_VARIABLE FLEX_version_output
   ERROR_VARIABLE FLEX_version_error
   RESULT_VARIABLE FLEX_version_result
   OUTPUT_STRIP_TRAILING_WHITESPACE)
 IF(NOT ${FLEX_version_result} EQUAL 0)
   MESSAGE(SEND_ERROR "Command \"${FLEX_EXECUTABLE} --version\" failed with output:\n${FLEX_version_error}")
 ELSE()

So, if the flex that is found does not support the --version flag, or fails to run, it is always a fatal error. It should only be a fatal error if the find_package(FLEX REQUIRED) is given.
