make problem for mkl

[MXY6]

Hi, recently I build a project using mkl through make, my simple CMakeLists is like this,

cmake_minimum_required(VERSION 3.14)
project(ex5 Fortran)
enable_language(Fortran)

find_package(MKL REQUIRED)
include_directories(${MKL_INCLUDE})

add_executable(ex5 main.f90)
target_link_libraries(ex5 ${MKL_LIBRARIES})
#target_link_options(ex5 PUBLIC $<LINK_ONLY:MKL::MKL>)

If I use target_link_libraries(ex5 ${MKL_LIBRARIES}), I can successfully build the project, but not for

#target_link_options(ex5 PUBLIC $<LINK_ONLY:MKL::MKL>), which shows this error,

ifort: error #10236: File not found: 'MKL::MKL'

could you help solve this?

Hi Meng,

We have tested with oneMKL 2021.4 and confirmed the issue. We have escalated this issue to the MKL team.

We will let you know when we have the solution for this problem.

Best regards

Hi Meng,

cmake function target_link_options inserts the target as is, target_link_libraries should be used in order to resolve MKL target correctly.

Please refer to CMakeLists.txt from oneMKL Fortran examples for the correct way how to include oneMKL to CMake project for classic Fortran API:

<install_path>/oneapi/mkl/2021.4.0/examples/examples_core_f.tgz/f/CMakeLists.txt: 

target_compile_options(${func} PUBLIC ${TEST_COPT} $<TARGET_PROPERTY:MKL::MKL,INTERFACE_COMPILE_OPTIONS>)

target_link_libraries(${func} PUBLIC ${TEST_LOPT} $<LINK_ONLY:MKL::MKL>) 

This should fix it.
