From source with cmake

You can also install xeus-cling from source with cmake. This requires that you have all the dependencies installed in the same prefix.

mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=/path/to/prefix ..
make install

On Windows platforms, from the source directory:

mkdir build
cd build
cmake -G "NMake Makefiles" -DCMAKE_INSTALL_PREFIX=/path/to/prefix ..
nmake
nmake install

Installing the Kernel Spec

When installing xeus-cling in a given installation prefix, the corresponding Jupyter kernelspecs are installed in the same environment and are automatically picked up by Jupyter if it is installed in the same prefix.

However, if Jupyter is installed in a different location, it will not pick up the new kernels. The xeus-cling kernels (for C++11, C++14 and C++17 respectively) can be registered with the following commands:

jupyter kernelspec install PREFIX/share/jupyter/xcpp11 --sys-prefix
jupyter kernelspec install PREFIX/share/jupyter/xcpp14 --sys-prefix
jupyter kernelspec install PREFIX/share/jupyter/xcpp17 --sys-prefix

For more information on the jupyter kernelspec command, please consult the jupyter_client documentation.
