[Mingw-cross-env-list] mxe with sfml linking errors

[damien LAURENT]

Dear list,

I've developped a project on linux and I now I would like to distribute
it on Windows. My project uses the following external libraries: fftw,
SFML and wxWidgets.
With the command 
$
cmake 
..-DCMAKE_TOOLCHAIN_FILE=/home/damien/mxe/usr/i686-pc-mingw32/share/cmake/mxe-conf.cmake
then
$ make
the compilation occurs nicely, but it makes errors when linking.
The error messages seems to refer to SFML objects (e.g. first line
sf::Color::Black). Here are the messages:
address@hidden:~/Bureau/cpp/winviolette/build$ make

Any ideas ?
