FFT Open MP

Greetings,

I have problems with running IPP 2019 FFT with OpenMP internal parallelisation, I have already tried approach: https://software.intel.com/en-us/ipp-dev-guide-using-intel-integrated-pe..., but I can't find configuration of libraries to link to make this work.

Using ippsFFTFwd_CToC_64fc and trying to set ippSetNumThreads to 2. (I noticed on forums for internal paralelisation u cannot use more than 2 is this true ?)

For compiling i'm using gcc or icc linking includes with _tl suffix and lib /lib/intel64/tl/openmp/ with _tl suffix.
I noticed you have to mix in some non _tl files still but cannot make it work, could you please provide list of files from include and lib to use to get fft working with openmp ?

My env:
Ubuntu 16.04 LTS
Gcc 6+
Icc from Parallel Studio XE 2020

Also adding small sample code (c++11) I use, I check parallelism with vtune-gui.

Thank you for response,

Adam Simek
