Why high-end cable manufacturers don't post measurements?

It's more because certain individuals post all over the place shilling one brand, and one brand only, rather than keeping an open mind on a number of highly recommendable manufacturers.

I don't know that I have ever seen a cable thread on this site that has actually benefitted audiophiles in making superior audio systems.

Ditto equipment reviewers.

That is a poor question because some manufacturers do state some measurements.

What measurements are you looking for ? The trouble is no set of measurements directly tells the consumer how well the cable will sound. Especially since there are thousands of different audio systems in the world today.

If you are looking for certain measurements, you can ask the manufacturer, or have them done yourself. Beware, they are not always cheap and easy to do !

Why do you say: " The trouble is no set of measurements directly tells the consumer how well the cable will sound"?
Please say I don't know about such measurements.
It's even worst, as you do not know what is it that makes one cable sound better over the other.
So what spec. you would look at (if published) and how would you know, by that spec. what cable to buy?

Don't worry. I know. 
DIY is a good idea. But what is the cable that you need? what is the parameter to look for and have in that cable?

The bad part is, that the cable makers not only do not provide much information about their products, but they don't know what is in that cable, that should be significant. So sad...

0, or even 00 and we are done.
