Build Failure with CMake and pydifem #2
Description
Issue: Build Failure with CMake and pydifem
Summary:
I'm experiencing a build failure when compiling the pydifem.cc file due to an error related to the isfinite function in Eigen with CppAD::AD. The issue occurs while building the project using CMake on a Linux environment.
Environment Details:
OS: Linux (Ubuntu/Debian)
Compiler: GCC (version 11.4)
Eigen Version: 3.4
CppAD Version: 2021.00.00.8
Python Version: 3.8 (Conda environment)
CMake Version: 3.22.1
