Sorry, haven't explained properly.
Yes I replaced my External/bin and External/lib directories with the ones from the latest download link. The problem is when I try to make the buid files with cmake (H3DAPI, Viewer or Load), it doesn't find the lib files for glut, and I have to set it myself; but, inside the External/lib folder there is no glut32 library.

Edit: Same problem when I run cmake for the Viewer. It can't find the wx... libraries, so I set them, most of them; I was able to find: wxWidgets_adv_LIBRARY, wxWidgets_base and so on. but I couldn't find the wxWidgets_popgridd_LIBRARY lib. Either I can't see it, or it isn't there.

That is the thing, the structure is slightly different now, so you can not replace External/bin and External/lib.

Those directories are named bin32 and lib32 now (and there are also bin64 and lib64 ).
So the entire External directory should be removed, and be replaced by the one in the downloads section, then delete cmake cache and regenerate. Sorry for not making that clear earlier.

Also remember to update your PATH environment variable.
