+Hi,\r
+\r
+I'm curious about the reason behind choosing to do your own configure\r
+tool instead of using tools like autotools or cmake?\r
+\r
+Because for me it increases the chance to introduce bugs in the build\r
+system since you are redeveloping tests to know whether a library is\r
+present or not, the system to check if a flag is supported by the\r
+compiler, to check if a function is present, to manage different\r
+platforms,... All of these things are provided by tools like autotools\r
+or cmake.\r
+\r
+For example, I noticed that the part that check if the compiler\r
+options are supported, is not working. Try adding a flag supported by\r
+gcc but not by clang and use clang to compile or vice-versa.\r
+\r
+Thanks\r
