如何使用CMake Tools插件配置复杂的项目？

如何解决如何使用CMake Tools插件配置复杂的项目？

我正在尝试配置vscode以使用CMake Tools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：调整了错误消息

EDIT2：

修改.vscode/settings.json以使用cmake.configureSettings不能解决问题：

{
    "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",}
}

解决方法

我发现了问题/可能的错误。

vscode和CMake Tools插件似乎缓存了一些文件，并且即使您删除了构建文件夹（包含CMakeCache.txt），该项目也不使用在{{1 }}。

所以，要使我的项目正常工作。

1. 我将此信息添加到了.vscode/settings.json：

.vscode/seetings.json

1. 已关闭vscode
2. 删除了构建文件夹
3. 打开了vscode
4. 回答是：“您要配置项目'llvm-project'吗？”

配置成功。

现在您可以使用vscode选择目标了。

不幸的是，每次打开vscode时，CMake插件都会触发新配置，但最好在另一个问题/论坛中解决此问题。

,

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"],//...
    }
}
