CMake找不到OneAPI库mkl_gf_lp64和mkl_gnu_thread

Question

我正在尝试将最初为Intel编写的源代码改编为最新的OneAPI，并在MacOS下编译它。

我对CMakeLists进行了修改，以找到这样的OneAPI库：

    option (USE_ONEAPI "Enable MKL solver support via OneAPI Base Toolkit" ON)
    ...
    if (USE_ONEAPI)
    message(STATUS "Seeking OneAPI libraries...")
    list(APPEND MKL_LIBS "mkl_core" "mkl_gf_lp64" "mkl_gnu_thread" "pthread")
    foreach (f ${MKL_LIBS})
        if (INTEL_ONEAPI_DIR)
            # user provided OneAPI directory
            set(oneapiMklDir "${INTEL_ONEAPI_DIR}/mkl/latest")
            message(STATUS "    Seeking for ${f} in custom path: ${oneapiMklDir}...")
            find_library (${f}_LIB ${f} PATH "${INTEL_ONEAPI_DIR}/mkl/lib/intel64/" DOC "MKLPARDISO (library)")
            include_directories ("${INTEL_ONEAPI_DIR}/mkl/include")
        else ()
            set(oneapiDir "/opt/intel/oneapi")
            set(oneapiMklDir "${oneapiDir}/mkl/latest")
            message(STATUS "    Seeking for ${f} in default path: ${oneapiMklDir}...")
            find_library (${f}_LIB ${f} HINTS "${oneapiMklDir}/lib" DOC "MKLPARDISO (library)")
            include_directories ("${oneapiMklDir}/include")
        endif ()
        if (${${f}_LIB} STREQUAL "${f}_LIB-NOTFOUND")
            message (FATAL_ERROR "OneAPI ${f} library not found")
        else()
            message (STATUS "OK: ${f} library successfully found")
        endif ()
        list (APPEND EXT_LIBS ${${f}_LIB})
    endforeach ()
    list (APPEND MODULE_LIST "MKLPARDISO")
    endif ()

这就是结果：

-- Seeking OneAPI libraries...
--     Seeking for mkl_core in default path: /opt/intel/oneapi/mkl/latest...
-- OK: mkl_core_LIB library successfully found
--     Seeking for mkl_gf_lp64 in default path: /opt/intel/oneapi/mkl/latest...
CMake Error at CMakeLists.txt:379 (message):
OneAPI mkl_gf_lp64 library not found

我不知道为什么CMake没有找到这些库。它们是否安装了OneAPI base和HPC工具包？

这很可能是老生常谈，你已经找到了解决办法，但既然我正在讨论一个问题，我想我会回答下一个人。

不包括mkl_gf_lp64，但mkl_intel_lp64包含。这两者并不相等，所以您可能需要mkl_intel_thread。

您还可以使用oneAPI链接顾问来准确地确定您需要什么。
