[Rock-dev] Rock CMAKE macros not working under windows

Discussion:

Hey,
the Rock CMAKE macros do not work under windows, which
is especially bad for base/types. The root of the problem is the
creation of symlinks, which is not supported on windows :
e.g. : cmake -E create_symlink
Anyone an idea how to overcome this issue, without changing
the current setup ?
Greetings

One needs admin rights to create junction points.
The only command runnable as a normal user is
mklink /J
I'll try to figure out if this is sufficient. Anyway, I was
more looking for a native cmake solution...

From quickly googling about it, it seems that we would need to replace
the create_symlinks call on windows by a junction creation (given what
we do, should work fine, but someone should please check it out). We
would be limited to NTFS.

On the cmake bugtracker you will find some bug reports about this
problem. I think there is no cmake solution and it is not planed to fix
this in the near future by the cmake developers.

So we have to handle it on our own.

It seems that mklink /D creates symbolic links for directories ...
Don't know why nobody seem to mention it in the cmake threads I read
...

Answering my own question: mklink is only available since Vista. I
don't see that as a problem for us.

You also need superuser rights to do an mklink /D and this is a problem.

Funnily enough mklink /J does create a junction (per documentation &
googling). So it seems that the web was right after all ;-)

It seems that symlinks are pretty limited on windows, so going for
them would not have been a good move anyways
