Summary0004418: cmake -create-symlink doesn't overwrite existing symlinks
DescriptionHi,

cmake -E create_symlink old new

doesn't change/create "new" if it already exists. So if "new" already exists and it points to "/usr/foo", but I want it to point to "/usr/bar", create_symlink doesn't do this, the symlink is unchanged.

This seems to be the case both on Linux and OSX. It can be worked around be removing the symlink first.

Alex

Well ln -s does the same thing, right?

Not exactly. Just "ln -s" fails with an error message in this case. "ln -f -s" creates the new symlink. Both is better than silently failing.


$ ln -s old new
$ ln -s oldx new
ln: `new': File exists
$ ln -f -s oldx new
$ ls -al
