[Vala] Binding 7zip library ?

[raum no-log org]

Hello,

I've downloaded and build 7Zip library and I've these files compiled
(under Windows using MingW32, with prefix /opt) :

/src/lib7zip-1.6.5/Lib7Zip/lib7zip.a
/src/lib7zip-1.6.5/Lib7Zip/lib7zip.dll
/src/lib7zip-1.6.5/Lib7Zip/lib7zip.h

"make install" command didn't copy these files under /opt/bin,
/opt/include, /opt/library

I've copied manually in the correct directory but tests programs output :
# test7zip.exe
initialize fail!

So I think I've made a mistake somewhere... But how to test it with a vala
test program ? I need to build a vapi file ? something like that ?

Thanks
