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 ls_rkeops_build_dir() lists all files in RKeOps build
directory.
You can use get_rkeops_build_dir() get the path to RKeOps build
directory, and you can use clean_rkeops() to delete its content.
