[Mingw-cross-env-list] linker error for qt5 application

[Thomas Spitzer]

Hello,
I try to cross compile a QT5/QTQuick application. In the first step I  
made a "hello World" application just to test if the cross environment  
works for me. It doesn't.

It's a cmake project. It works in my debian Linux. With:

cd build
rm -rf *
cmake ..
make

The test program compiles

If I try for minGW:

cd build
rm -rf *
~/mxe/usr/bin/i686-w64-mingw32.static-cmake ..
make

I get linker errors:

/home/thomas/mxe/usr/i686-w64-mingw32.static/qt5/lib/libQt5Network.a(qsslsocket_openssl.o):qsslsocket_openssl.cpp:(.text+0x125a): undefined reference to  
address@hidden'

address@hidden'

I've no idea, what to do. Can you give me a hint?
