Linking issue when using MinGW with Posix Threads

[g4-lisz@xxxxxxxxxxxx]

Hi there,

cmake detects pthreads and compiling goes well. But on linking, there
are unresolved references:

CMakeFiles/ssh.dir/objects.a(pthread.c.obj):pthread.c:(.text+0x43):
undefined reference to `pthread_mutex_destroy'

... and so on.

This can be solved by adding `-lpthread `at the end of the last line of
build/src/CMakeFiles/ssh.dir/link.txt

I don't know a lot about cmake. So I couldn't find a way to tell it to
add it at the rigth place.

CMAKE_SHARED_LINKER_FLAGS etc. did not do the trick because it puts it
in the wrong place (before CMakeFiles/ssh.dir/objects.a).

Regards,
Till
