Debugging C/C++ external library from PyCharm

Hello,
I'm working on some optimization system using python 2.7.
The OS on the developer machine is a Linux Mint 17.1.
For the task definition I use  a PuLP library and for the solving purposes I use CBC and GLPK solvers as a Black Boxes.
Both of the open source solvers realized in C/C++.
How can I see what is going with the task definition inside of these solvers.
How can I debug these libraries as a C/C++ based code using PyCharm?
Have you any add-ons for such purposes?
If yes, what kind of and how to install it?
Thanks ahead,
Yigal
