Add LLVM to project using cmake

问题:

I'm trying to add LLVM to a cmake project, using cygwin as a compiler. I downloaded LLVM from cygwin's installer (just installed all of the llvm related packages). The files are there, however I cannot include LLVM in my project. I tried using the official guide for 3.5.2 (the version it installed) and my CMakeLists.txt looks like

cmake_minimum_required(VERSION 3.2) project(Lang)  find_package(LLVM REQUIRED CONFIG)  message(STATUS "Found LLVM ${LLVM_PACKAGE_VERSION}") message(STATUS "Using LLVMConfig.cmake in: ${LLVM_DIR}")   include_directories(${LLVM_INCLUDE_DIRS}) add_definitions(${LLVM_DEFINITIONS}) set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")  set(SOURCE_FILES main.cpp)  add_executable(Lang ${SOURCE_FILES})  llvm_map_components_to_libnames(llvm_libs support core irreader)  # Link against LLVM libraries target_link_libraries(Lang ${llvm_libs})

However, I get a bunch of errors like these

Am I doing something wrong? All I want to do is to use LLVM in my project.

As indicated by Marco A. in the comments, the problem were missing libraries. This link helped resolve the issue, and everything seems to be working normally now. https://stackoverflow.com/a/25783251/1938163

Thank you.
