Re: [sr-dev] [kamailio/kamailio] Location for git submodules in the source tree (Issue #3164)

We could(should?) recommend the location for build artifacts `*.h *.a *.so` so the Makefiles can have some consistency. To take @miconda's example one step further

``` misc/vendor/wolfssl/ - vendor root directory misc/vendor/wolfssl/@wolfssl - the git submodule misc/vendor/wolfssl/root - the --prefix in autotools build systems ```

The submodule Makefile can then reference the build artifacts. ``` # maybe some make system var for ../../../misc/vendor VENDOR = ../../../misc/vendor

INCLUDES = -I$(VENDOR)/wolfssl/root/include LIBS = $(VENDOR)/wolfssl/root/lib/libwolfssl.a ```
