MKL 2024.2 doesn't work with CMake

[V-T]

Consider the following contents of two files in the same directory:

• `CMakeLists.txt`:

cmake_minimum_required(VERSION 3.12)
project(test Fortran)
set(MKL_ARCH "intel64")
set(MKL_LINK "dynamic")
set(MKL_THREADING "sequential")
set(MKL_INTERFACE "lp64")
set(MKL_MPI "intelmpi")
find_package(MKL)
add_executable(test test.f90)
target_link_libraries(test ${MKL_LIBRARIES})

• `test.f90`:

program p
real sdot
print*,sdot(1,[1.],1,[1.],1)
end

An attempt to compile the program with the following commands in the same directory

mkdir build
cd build
FC=mpiifx cmake ..
cmake --build .

results in an error `undefined reference to `sdot_'`.

It only happens with the newest MKL version 2024.2. The older MKL version 2024.1 works properly. Did something important change in the `MKLConfig.cmake` file? Am I missing something in the `CMakeLists.txt` file?

Hi,

From oneMKL 2024.2, we recommend users use MKL::MKL instead of MKL_LIBRARIES in target_link_libraries(test MKL::MKL)

Please use MKL::MKL target. You can also find an example in the oneMKL CMake documentation page.

Thank you very much! That solves the issue.
