Deps fail with Cairo.jl

[RGerzaguet]

Hello there,
I work on MacOS-X catalina. I have tried to install Gtk, after installing Cairo.
Cairo install without issue with 0.8 version (since 0.7, install on macos is fixed).
However, Gtk needs a Cairo with 0.6 max version, so I have a compat issue

(v1.1) pkg> add Gtk
 Resolving package versions...
ERROR: Unsatisfiable requirements detected for package Cairo [159f3aea]:
 Cairo [159f3aea] log:
 ├─possible versions are: [0.5.3-0.5.6, 0.6.0, 0.7.0, 0.8.0] or uninstalled
 ├─restricted to versions 0.8.0 by an explicit requirement, leaving only versions 0.8.0
 └─restricted by compatibility requirements with Gtk [4c0ca9eb] to versions: [0.5.3-0.5.6, 0.6.0] — no versions left

May it be possible to push a compat for last Cairo version ?
Note that I cannot install Cairo 0.6 on my side (macos issue I assume ?)

Cairo now uses BinaryProvider instead of Homebrew to provide libraries, so it's not compatible with current Gtk version. The plan is to move Gtk to BinaryProvider too, but until then you need to use Cairo v0.6.

I think you need to get the master of Homebrew.jl (]add Homebrew#master should do it), 10.15 was added in the commit but not yet released :

JuliaPackaging/Homebrew.jl@54d26aa

Alternatively, the tests are passing on mac OS for the BinaryProvider build, so you could give it a try.

#447

Yes, the BB works on OSX and will be the way to go. It requires Julia 1.3 though (which is not yet released)

Ok, thank you very much for the fast and detailed feedback.
Will wait for the new BB then
Thanks again :)
