在撰写 clang 时,他们的 Visual Studio 用户手册中有此文档:

cmake -G"Visual Studio 2017" -T LLVM ..
这不起作用。
我从 cmake 收到了一条错误消息:
CMake Error at CMakeLists.txt:3 (project):
Failed to run MSBuild command:

C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/MSBuild/Current/Bin/MSBuild.exe

to get the value of VCTargetsPath:

最佳答案

这不适用于 VS2019。在 vs2019 中,您必须将工具集指定为 ClangCL .
据我所知,此更改未在任何地方记录。
我只能通过反复试验来解决这个问题。

cmake -G"Visual Studio 2019" -T ClangCL ..
这是您将获得的输出。
PS D:\Github\glfw> cmake -S . -B build -T ClangCl
-- Building for: Visual Studio 16 2019
-- Selecting Windows SDK version 10.0.18362.0 to target Windows 10.0.19041.
-- The C compiler identification is Clang 10.0.0 with MSVC-like command-line

这是它的样子:

编辑:
您还可以像这样手动设置工具集:
# Must be called before project call
set(CMAKE_GENERATOR_TOOLSET "ClangCL")

project(FOOBAR
LANGUAGES "CXX"
)
