Dune build fails when `camlimages.5.0.5` is installed

opam install satysfi fails by the following error.

But camlimages is indeed intaled:

❮ opam list
# Packages matching: installed
# Name                      # Installed   # Synopsis
(snip)
camlimages                  5.0.5         Image processing library
(snip)

@gfngfn reported that this does not occur when camlimages.5.0.4-1 is installed. So the workaround is to install that version manually before installing satysfi:

❯ opam install camlimages.5.0.4-1
The following actions will be performed:
  ↘ downgrade camlimages 5.0.5 to 5.0.4-1

⊘ removed   camlimages.5.0.5
∗ installed camlimages.5.0.4-1
Done.


❯ opam install satysfi

Further investigation is wanted.

I tried to install SATySFi on macOS according to the following URL but failed for the reasons given in this issue. I solved the problem with the solution described above. I confirmed that the PR above was merged to master, but I guess you forgot to replace the tag v0.0.10. Could you please check?

[gfngfn]

Ah yes, I haven't released v0.0.11 for a dozen days. I'll be sure to do it soon.

(Changing commits pointed at by an existing tag is not a good idea; we should create another tag instead)

The current workaround is, however, very ad-hoc, and @leque-san suggested a better cure. I would like to try it before releasing v0.0.11.

Thank you anyway for encouraging me!

[gfngfn]

Unfortunately, camlimages.5.0.5 per se seems to have some issues with its installation, and we couldn't solve them immediately. I thus released v0.0.11, which continues to do the workaround about the version constraint.
