visual-studio-code - 如何使用 CMake Tools 插件配置复杂的项目？

问题描述

我正在尝试配置 vscode 以使用 CMake 工具插件开发 llvm/mlir 项目。该项目很大，需要将此配置传递给命令行：

git clone https://github.com/llvm/llvm-project.git
mkdir llvm-project/build
cd llvm-project/build
cmake -G Ninja ../llvm \
   -DLLVM_ENABLE_PROJECTS=mlir \
   -DLLVM_BUILD_EXAMPLES=ON \
   -DLLVM_TARGETS_TO_BUILD="X86;NVPTX;AMDGPU" \
   -DCMAKE_BUILD_TYPE=Release \
   -DLLVM_ENABLE_ASSERTIONS=ON \
   -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DLLVM_ENABLE_LLD=ON \
   -DPYTHON_EXECUTABLE=python3

我试图将此信息添加到.vscode/settings.json：

{
    "cmake.sourceDirectory": "${workspaceFolder}/llvm",
    "cmake.configureArgs": [
        "-DLLVM_ENABLE_PROJECTS=mlir",
        "-DLLVM_BUILD_EXAMPLES=ON",
        "-DLLVM_TARGETS_TO_BUILD='X86;NVPTX;AMDGPU'",
        "-DCMAKE_BUILD_TYPE=Release",
        "-DLLVM_ENABLE_ASSERTIONS=ON",
        "-DCMAKE_C_COMPILER=clang",
        "-DCMAKE_CXX_COMPILER=clang++",
        "-DLLVM_ENABLE_LLD=ON",
        "-DPYTHON_EXECUTABLE=python3",
    ]
}

但是配置不成功，似乎没有检测到我的参数。

如何将配置行转换为 CMake Tools 插件可以理解的内容？

编辑：调整错误信息

编辑2：

修改.vscode/settings.json使用cmake.configureSettings并没有解决问题：

{
    "cmake.sourceDirectory": "${workspaceFolder}/llvm",
    "cmake.configureSettings": {
        "LLVM_ENABLE_PROJECTS" : "mlir",
        "LLVM_BUILD_EXAMPLES" : "ON",
        "LLVM_TARGETS_TO_BUILD" : "\"X86;NVPTX;AMDGPU\"",
        "CMAKE_BUILD_TYPE" : "Release",
        "LLVM_ENABLE_ASSERTIONS" : "ON",
        "CMAKE_C_COMPILER" : "clang",
        "CMAKE_CXX_COMPILER" : "clang++",
        "LLVM_ENABLE_LLD" : "ON",
        "PYTHON_EXECUTABLE" : "python3",
    }
}

解决方案

在.vscode/seetings.json中，使用数组语法来指定多个选项。例如，

{
    "cmake.sourceDirectory": "${workspaceFolder}/llvm",
    "cmake.configureSettings": {
        //...
        "LLVM_TARGETS_TO_BUILD" : ["X86", "NVPTX", "AMDGPU"],
        //...
    }
}
