Linux: Make sure that the openMPI libraries, including libopenmpi-dev, are installed. Run ./make.sh <name_of_folder_with_main_file>, in the main directory, std_case is built if no argument to make.sh is given.
This script will make a build folder, run cmake from that folder and then run make. This can also be done by hand:
/BADChIMP-cpp$ mkdir <build-folder-name>
/BADChIMP-cpp$ cd <build-folder-name>
/BADChIMP-cpp$ cmake -DLBMAIN:STRING="<name_of_folder_with_main_file>" ./..
/BADChIMP-cpp$ makeWindows: Make sure that open MPI is installed. Download and run msmpisetup.exe and msmpisdk.msi. Install cmake for Windows. Run cmake from main directory to generate Visual Studio C++ project, or simply use VSCode.
