Summary: cmake crash in GetNumberOfFilesInDirectory
Description:
In Source/kwsys/Directory.cxx, the result value of opendir() is not checked,
which can lead to readdir being called with a NULL pointer as first argument,
which, at least on NetBSD, leads to a segfault.
Steps to Reproduce:
I don't know how to cause this, but it happened to me in parallel builds on a
tmpfs e.g. when building wesnoth.
Additional Information:
The attached patch returns '0' as count for directories when opendir fails,
which makes wesnoth build for me. Perhaps dirp==NULL should be reported, but I
don't know how to best do that, so I'll leave that up to you.
