链接从命令行翻译到 Make 的库

Question

我正在尝试将英特尔数学内核库 (mkl) 升级到运行。有一个工具 (https://software.intel.com/en-us/articles/intel-mkl-link-line-advisor) 可以打印必要的、依赖于环境的 cmd 命令以将其用于 C++ 脚本。对我来说它说：

使用此 link 行： ${MKLROOT}/lib/libmkl_intel_lp64.a ${MKLROOT}/lib/libmkl_intel_thread.a ${MKLROOT}/lib/libmkl_core.a -liomp5 -lpthread -lm -ldl

编译器选项： -m64 -I${MKLROOT}/include

我的目标是用 CMake 脚本编写它。我哪里出错了/我必须写什么才能使这项工作正常进行？

cmake_minimum_required(VERSION 3.15)
project(PSD_Projections)

set(CMAKE_CXX_STANDARD 14)
set(MKL_DIR /opt/intel/mkl)

# Part for the linker line
# This seems to be somewhat okay
# However I can't figure out what to do about the other linker line arguments
find_library(LIB1 mkl_intel_lp64 ${MKL_DIR}/lib)
find_library(LIB2 mkl_intel_thread ${MKL_DIR}/lib)
find_library(LIB3 mkl_core ${MKL_DIR}/lib)
link_libraries(${LIB1} ${LIB2} ${LIB3})

# Part for the compiler options.
# ${MKL_DIR}/include is found and exists
# I don't know what to do about the -m64 
include_directories(${MKL_DIR}/include)

add_executable(PSD_Projections main.cpp)

Answer 1

顺序 ILP64 版本的示例：

target_include_directories(PSD_Projections PUBLIC "${MKL_DIR}/include")
target_compile_definitions(PSD_Projections PUBLIC MKL_ILP64)
target_link_directories(PSD_Projections PUBLIC "${MKL_DIR}/lib/intel64")
target_link_libraries(PSD_Projections PUBLIC mkl_intel_ilp64 mkl_sequential mkl_core m dl)
target_link_options(PSD_Projections PUBLIC "-Wl,--no-as-needed")

它可以很容易地根据您的需要进行调整。

如何设置 C++ 标准版本和编译器选项的示例：

target_compile_features(PSD_Projections PUBLIC cxx_std_14)
target_compile_options(PSD_Projections PUBLIC -Wall -Wpedantic -Wextra -m64 -march=native)
