Undefined reference to sf::Thread::* when using self compiled library

[Ethon]

Hi,
I always get error messages like this when using sf::Music with self-compiled SFML2-RC. (It works when using precompiled libraries, but that is no option)

../Libs/SFML/lib/libsfml-audio.a(SoundStream.cpp.o)||In function `sf::SoundStream::play()':|

Of course I link sfml-system. Any guess what could be wrong?

I am building it that way:

cmake . -DBUILD_SHARED_LIBS=OFF -DCMAKE_BUILD_TYPE=RelWithDebInfo -DGLEW_INCLUDE_PATH=../../GLEW/include -DGLEW_LIBRARY=../libGLEW_d.a -DSFML_INSTALL_PKGCONFIG_FILES=OFF

Thanks,

Ah, link order ... I didn't find a solution for hours, but 1 minute after posting my question here, the solution comes into my mind ...

Problem solved!
