A C++ library for performing configuration interaction (CI) calculations.

To install this library:

1. clone the master branch, which contains the latest release

    https://github.com/GQCG/ci.git --branch master --single-branch
    cd ci
   

2. perform an out-of-source cmake build:

    mkdir build && cd build
    cmake -DINSTALLATION_PREFIX=prefix ..
    make && make test && sudo make install
   

   where

   • prefix is the installation prefix (defaulted to /usr/local) you want the library to be installed at:
     • the library libci.a will be installed in prefix/ci/lib
     • the header files (and cmake files, see Usage) will be installed in prefix/ci/include

Basic usage of this library can be found in the tests directory. If you use CMake in other projects, you can add the following CMake command to the CMakeLists.txt-file:

find_package(ci 1.2.1)

CMake then provides the commands ci_INCLUDE_DIRS to be used in your target_include_directories and the library ci to be used in your target_link_libraries.
