CMake Config for oneMKL

If you want to integrate oneMKL into your CMake projects, starting with the Intel® oneAPI Math Kernel Library (oneMKL) 2021.3 release, MKLConfig.cmake is provided as part of the package and installation. MKLConfig.cmake supports all oneMKL configurations, compilers, and runtimes, as the oneMKL product itself. Help/usage is provided in the top section of MKLConfig.cmake.

Example

my_test/
  |_ build/                       <-- Out-of-source build directory
  |_ CMakeLists.txt        <-- User side project's CMakeLists.txt
  |_ app.c                       <-- Source file that uses oneMKL API

CmakeLists.txt

Command line

# Source the compiler and runtime beforehand

build$ cmake .. -DCMAKE_C_COMPILER=icc

build$ cmake --build . && ctest

# If MKLConfig.cmake is not located by CMake automatically, its path can be manually specified by MKL_DIR:

build$ cmake .. -DCMAKE_C_COMPILER=icc -DMKL_DIR=<Full path to MKLConfig.cmake>

Note

Ninja 1.10+ is required when using Fortran.
