Hi Alan, my first impression is that it is indeed some peculiarity of MinGW/MSYS/Wine that you have uncovered - I have never seen an infinite loop caused by CMake trying to establish whether Lua is present or not (I do not have it installed, nor do I tell CMake not to look at it). But I will look into the issue - it might have to do with MSYS, as I ordinarily just use MinGW from an ordinary DOS-box.
It will be a few days, though, before I can really have a look at this. Regards, Arjen On Sat, 20 Oct 2012 17:55:51 -0700 (PDT) "Alan W.
