Clang with MSVC-like cross build for windows bin from ubuntu have configuration confusion

[zuowanbushiwo]

• I've read the CONTRIBUTING guide.

Use the following dockerfile to build a cross-compiled windows program image, based on clang + wine + msvc tools：

There is no libzlibstatic.a in the directory, but has zlibstatic.lib 。 I think it is correct build(), but there are some errors in package(), right? Didn't deal with the situation of clang cross compile windows bin ?

[dmn-star]

When I use conan under windows with clang-cl, my profiles look like this.
...
compiler=Visual Studio
compiler.toolset=ClangCL
...
It's worth a try.

Probably because you called linux cmake. But windows cmake will also not work, because you don't have VS installed.

CMake queries the VS Installer tool through a COM interface to get a list of VS installations. If none is found then we report a brief error:

Generator

Visual Studio 16 2019

 could not find any instance of Visual Studio.

This PR #11492, merged for next 1.53 contains a few changes to better support clang in Windows, mainly for the new CMakeToolchain integration, but some minor changes for others too.

There are some other pending issues about the Windows subsystems environment management, we are also trying to improve them in #12178, so if you are using Clang in some subsystem and depend on the environment, you might want to track this PR too.

Closing this issue now, but we know that there might still be some gaps, so please try to update to the new integration (this is necessary for 2.0 anyway), and report what might still be failing against this new integration. The best starting point would be the tests in https://github.com/conan-io/conan/blob/develop/conans/test/functional/toolchains/cmake/test_cmake_toolchain_win_clang.py, or using any of the predefined templates conan new hello/0.1 -m=cmake_lib|autotools_lib|msbuild_lib|meson_lib, and open a new issue. Many thanks!
