与 cmake 铿锵。 target_include_directories "没有这样的文件或目录"

这是我的 c++ 项目。

src/main.cpp 顶部：

#include "ccli/runToolOnCode.hpp"          
#include "ccli/GlobalContext.hpp"          
#include "ccli/exec_expr.hpp"              
#include "ccli/Utility.hpp"                

#include "clang/Frontend/FrontedActions.h"  //<- error occures here                                   

问题是 add_library() 中使用的所有文件都可以包含和使用 clang 标头，但 main.cpp 不能。 我也不明白为什么 main.cpp 被允许包含 /include/ccli headers，据我了解，这意味着这段代码运行良好：

target_include_directories(                                                                          
    main PUBLIC                                                                                      
        ${PROJECT_SOURCE_DIR}/include                                                                
)

但这不是？：

target_include_directories(main PRIVATE ${LLVM_INCLUDE_DIRS})

最后 cmake 的输出。

make 的输出

Answer 1

好像是错字，试试：#include "clang/Frontend/FrontendActions.h"

希望有帮助
