Clang build on Windows

[sphaero]

Not so much of an issue but rather a missing feature. Building libzmq on Windows with Visual Studio's Clang compiler works fine. however the tests give some errors.

Environment

• Windows 10
• Visual Studio 2019 with Clang compiler
• libzmq current master

Minimal test code / Steps to reproduce the issue

1. cmake .. -G "Visual Studio 16 2019" -A x64 -T "ClangCL" -DCMAKE_C_COMPILER="C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/VC/Tools/Llvm/x64/bin/clang.exe" -DCMAKE_CXX_COMPILER="C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/VC/Tools/Llvm/x64/bin/clang++.exe" -DBUILD_STATIC=ON -DBUILD_SHARED=ON -DCMAKE_INSTALL_PREFIX=C:\builds
2. cmake --build . --config Debug --target install
3. ctest -C Debug -V

93% tests passed, 7 tests failed out of 97

Total Test time (real) = 241.50 sec

The following tests FAILED:
         42 - test_shutdown_stress (Timeout)
         64 - test_monitor (Failed)
         66 - test_reconnect_ivl (Failed)                                                                             
         71 - test_ipc_wildcard (Failed)
         72 - test_pair_ipc (Failed)
         73 - test_reqrep_ipc (Failed)
         74 - test_rebind_ipc (Failed)
Errors while running CTest

What's the actual result? (include assertion message & call stack if applicable)

I guess it fails on IPC?
