HLS examples in centos container

Hi,

I set up a centos7 Docker container to run the Intel HLS compiler (Quartus Pro 21.1). However, when I try to compile the projects from the examples directory I get the following error:

i++ -march=x86-64 tutorial.cpp -o tutorial-x86

HLS x86-64 compile FAILED.

My guess is that I miss something in LD_LIBRARY_PATH, but up to now I could not find what is needed. Any hints?
