 The `MKL_ROOT` default to the environment variable `MKLROOT` (chosen by Intel). The additional variable `Heffte_MKL_THREAD_LIBS` allows to choose the MKL threaded backend, tested with `mkl_gnu_thread` and `mkl_intel_thread`, the default is to use GNU-threads on GCC compiler and Intel otherwise. Note that `mkl_intel_thread` also requires `libiomp5.so` and heFFTe will search for it in the system paths and `LD_LIBRARY_PATH`, unless the variable `Heffte_MKL_IOMP5` is defined and pointing to `libiomp5.so`. GNU-threads do not use `libiomp5.so` but the GNU `libgomp.so` which CMake finds automatically.
 
+**Note** if paired with oneMKL or using a clang compiler and CMake, the `Heffte_MKL_IOMP5` variable should not be needed.
