cmake：在 Windows 上找不到 LIBCLANG_PATH答案

【问题标题】：cmake: LIBCLANG_PATH not found on windowscmake：在 Windows 上找不到 LIBCLANG_PATH
【发布时间】：2023-04-04 02:31:01
【问题描述】：

我正在尝试编写一个简单的 clang AST cursor traveler。

https://github.com/dyhe83/clang-AST-cursor-traveler

以下 cmake 代码在 Linux 上运行良好。

PROJECT(traveler)

FIND_LIBRARY(LIBCLANG_PATH
    clang HINTS /usr/local/lib/
)

ADD_EXECUTABLE(traveler 
    traveler.cpp
)

TARGET_LINK_LIBRARIES(traveler
    ${LIBCLANG_PATH}
)

我也想在 windows 上运行这个例子。

我的 LLVM 构建在“C:\Program Files (x86)\LLVM”中

但是在我更改了 CMakeLists.txt 的 FIND_LIBRARY 部分之后。

FIND_LIBRARY(LIBCLANG_PATH
    clang HINTS "C:\\Program Files (x86)\\LLVM\\lib"
)

出现一些错误：

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
LIBCLANG_PATH
    linked by target "traveler" in directory D:/WorkSpace/C/clang-AST-cursor-traveler/src

-- Configuring incomplete, errors occurred!
See also "D:/WorkSpace/C/clang-AST-cursor-traveler/build/CMakeFiles/CMakeOutput.log".

并且“C:\Program Files (x86)\LLVM\lib”有这些库。

有谁知道windows上正确的clang库路径在哪里？？

【问题讨论】：

不应该是clang HINTS "C:/Program\ Files\ (x86)/LLVM/lib" 吗？
@super：在 CMake 中，无需使用 "\ " 转义空格 - 双引号内的空格只是空格。但你是对的，在 CMake 代码中“通用”路径分隔符 (/) 是首选。
我试过clang HINTS "C:/Program\ Files\ (x86)/LLVM/lib" ，但还是不行:(

【解决方案1】：

尝试在 windows 中设置 env virable。我的意思是你添加/编辑 PATH env virables 的地方

LIBCLANG_PATH=C:\Program Files (x86)\LLVM\lib
