我正在尝试创建一个CMAKE 来构建一个Visual Studio 2017 x64 解决方案，其中我使用一些Intel MKL 函数来计算使用LU decomposition 的一般矩阵的逆。构建项目时出现以下错误：

这是因为下面的CMAKE吗？

cmake_minimum_required(VERSION 3.11)

PROJECT(MYPROJECT)

set(MKL_INCLUDE_DIRS "C:/Program Files (x86)/IntelSWTools/compilers_and_libraries/windows/mkl/include")
set(MKL_LIBRARIES "C:/Program Files (x86)/IntelSWTools/compilers_and_libraries/windows/mkl/lib/intel64")

include_directories(${MKL_INCLUDE_DIRS})

add_executable(test MACOSX_BUNDLE)

target_link_libraries(
            test

            ${MKL_LIBRARIES}/mkl_tbb_thread.lib"
            ${MKL_LIBRARIES}/mkl_tbb_thread_dll.lib"

我在系统PATH中有包含DLLs的bin文件夹：

C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2019.0.117\windows\redist\intel64_win\mkl

【问题讨论】：

如何将详细的错误消息添加到您的问题中。除非我们知道未解析的符号是什么，否则很难提供帮助。
我不知道答案，但很明显你有错误的库列表。你已经包含了一些你不应该有的，这就是为什么你有“已经定义”的错误消息，而错过了一些你需要的，这就是为什么你有“未解决”的错误消息。我认为需要好好看看 MKL 文档。
您正在链接同一个库的 4 个变体。仅链接静态或动态以及 ilp64 或 lp64，具体取决于您的平台。

标签： c++ visual-studio visual-c++ cmake intel-mkl

【解决方案1】：

你链接了一些不必要的东西。您可以通过设置链接标志来解决此错误。

LINK_FLAGS "/force:multiple"

你丢失了一些必要的东西，请链接libiomp***.dll。 You can refer to this post
