Conflict between ossuuid and libuuid

[xylar]

This library brings in ossuuid, which conflicts with libuuid:

Would it be possible to build against libuuid instead?

@doutriaux1 and @dnadeau4, if I put in a PR to switch from ossuuid to libuuid, would that be welcome? I think I will go ahead and do that unless I hear otherwise.

@xylar two-three years ago I wanted to change ossuuid to libuuid I remember that I could get the uuid with both library for the tracking_id metadata in CMOR. I don't remember what stopped me from changing the library. Where are you using libuuid?

[xylar]

libuuid comes in through pyqt, which is used by spyder, jupyter and matplotlib (possibly among others). cdat it also trying to use both ossuuid (via libcf) and libuuid (via spyder, jupyter and matplotlib) so the problem should already be there for you guys, it maybe just went unnoticed.

I discovered a handy little tool for helping me figure out these dependencies this morning:
