Hi, When using CFLAGS=-Werror $ check_library_exists(m sqrt "" HAVE_LIBM) fails to give the correct result.
A very similar issue has been reported before for CHECK_FUNCTION_EXISTS http://www.cmake.org/Bug/view.php?id=8246 There the recommendation was to use CHECK_SYMBOL_EXISTS instead. My questions: 1) Is there an replacement for check_library_exists which gives the correct results for built-ins even with -Werror? 2) Should check_library_exists correctly work in this case and should I open a bug for it?
