Willy Tarreau b14e89e322 BUILD: makefile: initialize all build options' variables at once ... A lot of _SRC, _INC, _LIB etc variables are set and expected to be initialized to an empty string by default. However, an in-depth review of all of them showed that WOLFSSL_{INC,LIB}, SSL_{INC,LIB}, LUA_{INC,LIB}, and maybe others were not always initialized and could sometimes leak from the environment and as such cause strange build issues when running from cascaded scripts that had exported them. The approach taken here consists in iterating over all USE_* options and unsetting any _SRC, _INC, _LIB, _CFLAGS and _LDFLAGS that follows the same name. For the few variable names options that don't exactly match the build option (SSL & WOLFSSL), these ones are specifically added to the list. The few that were explicitly cleared in their own sections were just removed since not needed anymore. Note that an "undefine" command appeared in GNU make 3.82 but since we support older ones we can only initialize the variables to an empty string here. It's not a problem in practice. We're now certain that these variables are empty wherever they are used, and that it is possible to just append to them, or use them as-is.		2022-12-23 16:53:35 +01:00
