LWJGL uses its own variables for the path to the native libraries:
System.setProperty("org.lwjgl.librarypath", new File("pathToNatives").getAbsolutePath());
If you kept the file structure from the LWJGL package you can use something like this:
switch(LWJGLUtil.getPlatform())
{
case LWJGLUtil.PLATFORM_WINDOWS:
{
JGLLib = new File("./native/windows/");
}
break;
case LWJGLUtil.PLATFORM_LINUX:
{
JGLLib = new File("./native/linux/");
}
break;
case LWJGLUtil.PLATFORM_MACOSX:
{
JGLLib = new File("./native/macosx/");
}
break;
}
System.setProperty("org.lwjgl.librarypath", JGLLib.getAbsolutePath());
