how to manage dll internal dependencies (LUA C module)

Hi,

I'm creating a LUA C module using Qt4, so, my dll depends on libstdc++, libwinpthread, QtCore4 and QtGui4.
I would have loved to put all my dll in a "lib" folder near the executed Lua script but i can not achieve to do that.
At least, how could it be possible to avoid putting the dll in the system32 dir or in the Lua interpreter directory ?
(and maybe, later, I'll need the imageformats dll dir ...)

I use Qt 4.8.6, mingw4.8.2 and lua 5.2.4, 32bits.
The LUA IDE I use is eclipse (lua developpement tools) if it may offer any auxiliary solution...

(And static linking is not an option for licence reasons)

Thanks in advance.

Putting the DLLs in the same location as your DLL, not a lib subfolder, should work on Windows. You may also be able to do something magical and non-Qt with manifest files to load specific DLLs from known locations.
