我目前正在尝试编译一个程序，包括#include <clang-c/Index.h>使用 cmake

cmake_minimum_required(VERSION 3.4.3)
project(ast-dump)
set(CMAKE_EXPORT_COMPILE_COMMANDS ON)
find_package(LLVM REQUIRED CONFIG)
find_package(Clang REQUIRED)

include_directories(${LLVM_INCLUDE_DIRS})
add_definitions(${LLVM_DEFINITIONS})
include_directories(${CLANG_INCLUDE_DIRS})
add_definitions(${CLANG_DEFINITIONS})

add_executable(ast-dump ast-dump.cpp)

llvm_map_components_to_libnames(llvm_libs all)

target_link_libraries(ast-dump ${llvm_libs})

set_target_properties(ast-dump PROPERTIES
    CXX_STANDARD 14
)

我收到以下错误：

Undefined symbols for architecture x86_64:

但是，当我尝试使用以下命令行进行编译时，它工作正常：

c++ -isystem /usr/local/opt/llvm/include -L/usr/local/opt/llvm/lib/ -std=c++14 ast-dump.cpp -lclang -o ast-dump

但是使用命令行，如果我尝试添加#include <cmath>，就会出现ast-dump.cppcatalina<cmath>错误，我不知道如何解决。

任何帮助不胜感激！提前非常感谢。
