[czmq] Add new port

[myd7349]

Fix #5164 .

Whoops! After updated to 2018-12-15, the linux x64 build is failed. It may be caused by libcurl package:

• Merge czmq and czmq-static target.
• tool feature
• WITH_LIBSODIUM, WITH_LZ4, WITH_UUID, WITH_LIBCURL option
• install uuid on Windows
• sodium feature depends on [zeromq] Add sodium support and fix static build #4214
• sodium static build on Windows: [libsodium] Fix #3374, #3385 #5003
• curl linux build depends on OpenSSL, curl: linking static libraries on Linux needs extra CMake linking arguments? #4312
• ZMQ_STATIC depends on [zeromq] Add sodium support and fix static build #4214

I'm new to vcpkg, but I was attempting to use this branch by making a local merge with master. I ran into an issue with libsodium where I ended up commenting out the debug DLL/lib installs from ports/libsodium/portfile.cmake , as they were missing. This could be because I have

set(VCPKG_BUILD_TYPE release)

in triplets/x64-windows.cmake .

In any case czmq fails for me like so:

-- Could NOT find LIBZMQ (missing: LIBZMQ_LIBRARIES) 
CMake Error at CMakeLists.txt:132 (message):
  libzmq not found.

I had run vcpkg install zeromq though and it reports it's installed:

zeromq:x64-windows 2019-01-30 The ZeroMQ lightweight messaging kernel is a lib...

The zeromq DLL I found was buildtrees\zeromq\x64-windows-rel\bin\libzmq-mt-4_3_2.dll . There was also a .lib under the lib folder. I'm not sure why CMake can't find libzmq.

@tg2k Thanks for your interest in this PR. This PR still has room for improvement.

1. ZeroMQ's sodium feature is not that perfect currently. The reason is explained here: [zeromq] Add sodium support and fix static build #4214 (comment) . I also created a PR for migrating libsodium's build system to CMake: [libsodium] Migrate build system to CMake #5600 , and it is almost done.

2. I used several patch files under this PR, which is not that preferable. I was considering to fix some of the problems in the upstream repo, but I did not start this work yet.

I am on a bussiness trip these days. I will improve this PR when I am back.

A big update today!
Test project: https://github.com/myd7349/Ongoing-Study/tree/master/c/ZeroMQ/czmq/ipc_test

Test on Windows with vcpkg install czmq[curl,draft,httpd,lz4,tool,uuid]

• x86-windows
• x86-windows-static
• x64-windows
• x64-windows-static

Test on Ubuntu with vcpkg install czmq[curl,draft,lz4,tool,uuid]

• x64-linux

httpd feature failed on Linux because of: #6516

It is very strange: Both vcpkg-Linux-PR and vcpkg-windows-PR are happy, but Vcpkg-PR-Eager is not happy.

Hi! @ras0219-msft I think I have finished this port now. Cheers!

Looks good, @myd7349! I caught a typo in use of the feature flag, it will be mergeable when finished. Thanks for adding vcpkg_check_features, by the way. It's very helpful!

Hi! @grdowns Thanks! Should I squash those commits to keep the commit message clean?

[grdowns]

No need! We squash commits when we perform a merge (unless we make a mistake) 😆
