[DFTB-Plus-User] OpenMP compilation ?

I had find the sequence in manual:

   set up the ``TEST_OMP_THREADS`` variable to ``2`` (in `config.cmake`), issue

The test output files already detects 4 threads after modification of 
the TEST_OMP_THREADS to 4:

OpenMP threads:              4

And dftb+.exe  occasionally indicate more than 25% CPU load (4 core 
machine) ...

So it looks like it works

Thanks ...
