When compiling a user-defined operators, a shared object (.so) library
(or dynamic link library, .dll) file is created in RKeOps build
directory (located in the .cache folder in your home). For every
new operators, such a file is created.
Calling get_rkeops_build_dir() gives the location of this specific
directory on your system.
You can use ls_rkeops_build_dir() to list RKeOps build
directory content, and you can use clean_rkeops() to delete its
content.
