[Mingw-cross-env-list] Undefined references when using QtNetwork

[Benjamin Kloster]

Hi everyone,
I'm trying to build a Qt project depending on the QtNetwork library. The build 
system is not qmake, but CMake since it needs to integrate into a larger 
project. I followed the tutorial about setting up MXE and had some trouble 
with both the stable and the master branch (some libraries wouldn't compile 
when using just "make").

I decided to try and compile my project anyway, since MXE seemed to build Qt 
and some of my own libraries successfully. However, upon compiling my Qt 
project, I get a bunch of "undefined reference" errors seemingly related to SSL 
(which I don't use yet, but will require later on). An excerpt of the error 
message:

and so on for a few more pages.

"make openssl" in the MXE directory says there's nothing to be done for 
openssl, so it seems to be compiled properly. Same for Qt. So, how can I fix 
this?

Regards,
Ben
