If test succeed without warnings, then the flag is added to 15 # VARIABLE-TO-EXTEND. Otherwise, if compile and link without test flag cannot 16 # be done without any warning, the flag is considered to be unsuppoted. 17 # 18 # Example usage: 19 # 20 # MHD_CHECK_ADD_CC_LDFLAG([-pie], [additional_LDFLAGS]) 21 # 22 # 23 # LICENSE 24 # 25 # Copyright (c) 2022 Karlson2k (Evgeny Grin) <k2k@narod.ru> 26 # 27 # Copying and distribution of this file, with or without modification, are 28 # permitted in any medium without royalty provided the copyright notice 29 # and this notice are preserved.
