**To Reproduce** Steps to reproduce the behavior: 1. Change to develop branch, go to logconcave directory ``` cd ./volesti/examples/logconcave ``` 2. Build executable files ``` cmake . && make ```...

i am using gcc-9 on x86_64,linux gnu. I have already set set(MKLROOT /opt/intel/oneapi/mkl/2022.0.2).However, a new error comes out. "error while loading shared libraries: libmkl_intel_ilp64.so.2: cannot open shared object file: No...

While there is no errror during compilation, the issue(some logconcave examples are not working with MKL) is not solved.

This is the exact Library i used. https://www.intel.com/content/www/us/en/developer/tools/oneapi/onemkl-download.html?operatingsystem=linux&distributions=webdownload&options=offline

I have updated the mkl system,here is the updated cmake result. ``` -- The C compiler identification is GNU 9.4.0 -- The CXX compiler identification is GNU 9.4.0 -- Detecting...

I think the issue is with the random point generator from [volesti](https://github.com/GeomScale/volesti/tree/73608a4667ed8fe495a9fbdcb141a14c3e441f1b)/[include](https://github.com/GeomScale/volesti/tree/73608a4667ed8fe495a9fbdcb141a14c3e441f1b/include)/[sampling](https://github.com/GeomScale/volesti/tree/73608a4667ed8fe495a9fbdcb141a14c3e441f1b/include/sampling)/random_point_generators.hpp During the random sampling phase, all the points are zero. This is linked to the issue #223

I have narrowed down the issues, In [volesti](https://github.com/GeomScale/volesti/tree/45dd96ddb70bbdbf3257a9087fc7bdf679c0a32c)/[include](https://github.com/GeomScale/volesti/tree/45dd96ddb70bbdbf3257a9087fc7bdf679c0a32c/include)/[random_walks](https://github.com/GeomScale/volesti/tree/45dd96ddb70bbdbf3257a9087fc7bdf679c0a32c/include/random_walks)/exponential_hamiltonian_monte_carlo_exact_walk.hpp, line 113,T

Autodiff library is automatically downloaded in a similar fashion as Boost and Eigen.
