C++ build error

[Geonhee-LEE]

Hi, @alexliniger. Thanks for your contribution. I am interested in MPCC and want to run on C++ execution on the Ubuntu 18.04. According to your README, I tried to make the CMakeLists but failed like following:

After failed to make, I changed the CMakeLists and finally succeeded to build. But, I encountered the problem when I launched with './MPCC'. I found that problem is associated with matplotlib-cpp. However, I couldn't find the solution although strive to solve this problem with some modification and trials.

Let me know what is the problem if possible.

[alexliniger]

the two branches use different approaches for matplotlib-cpp in the CMake file, can you try out the other one as well. I will have a look as soon as possible. But over the years I had also several times issues with matplotlib-cpp. Best, Alex

Thanks for your reply. I tried to change from master branch to /wip/install-target branch. It also happened a same problem.
