They do - today I have also tested that for the LDFLAGS, and this works, too. If you pass the OpenSSL directories twice to the main configure script, everything works great:

I checked the config.log files and the shared objects with ldd - all headers are found and the correct library files are used. For that reason, everything is great for me - thank you very much for your help,

best regards,
