Installing with pip requires call to ldconfig if preCICE is built from source

I built preCICE from source yesterday (on Linux Mint, with parameters suggested here) and installed it succesfully, but then, running pip install --user pyprecice generates an error libprecice.so.2 not found. Running sudo ldconfig before running pip is enough to fix it.
The issue doesn't appear if we install a .deb package for libprecice. I noticed that the post-installation script of the .deb does include a call to sudo ldconfig, which explains a lot.

Suggested fix : Either add a call to ldconfig in the installation instructions (on the website) or the the install script (probably hard, since ldconfig requires superuser, it would break install into a user-chosen path without superuser). Unless something is wrong on the binding side, but I doubt it.

El informe trata sobre las instrucciones de instalación de la compilación desde el código fuente, el script de instalación y el script de postinstalación de .deb; comienza comparando esas rutas con la instalación de los bindings de pip. Se considera terminado cuando una compilación desde el código fuente seguida de pip install funciona sin una llamada manual a ldconfig, o cuando el paso requerido está documentado claramente.
