OK, I misunderstood something. Apparently decmpfs.h is a private system header that's not installed on normal user systems. That means I'll be able to drop the check and HAS_DECMPFS token. Thanks.

So I figured out that (your fork of) LZVN is required

sys/decmpfs.h still missing
i grabbed the file from https://github.com/apple/darwin-xnu/blob/master/bsd/sys/decmpfs.h
and put it at afsctool/sys/decmpfs.h
doesn't seem right, will look into it more

Yes... I'll get back to this one of these days (and see if indeed I made a PR to merge my changes upstream as I meant to).

`sys/decmpfs.h` still missing
i grabbed the file from https://github.com/apple/darwin-xnu/blob/master/bsd/sys/decmpfs.h
and put it at `afsctool/sys/decmpfs.h`
That's weird, because cmake should test for the existence of `<sys/decmpfs>` on the include path, and the code should use the copy in `afsctool/private` if the file hasn't been found. That works for my on 10.9 where there is no such system header file.
Can you reproduce the include failure with a fresh build (and without the copy in afsctool/sys that you created yourself)? If so, where does cmake find the file where it isn't found by the compiler afterwards?!

What problem? Cmake completes successfully here. This is interesting though:

Do you have a file /usr/include/sys/decmpfs.h ?

Yes, that was the problem I was referring to.
I do not have it, should I?
$ ls /usr/include/sys/decmpfs.h
ls: /usr/include/sys/decmpfs.h: No such file or directory

What Mac OS version do you run again? It's my understanding that the file should be there on recent versions, but it may be in a different location. What does either of the following print?
```
mdfind -name decmpfs.h
```
```
find /usr/include -name decmpfs.h
```
from afsctool.

$ mdfind -name decmpfs.h

matt@Matts-MacBook-Pro:~$ find /usr/include -name decmpfs.h
