 You can build the install target to put the resulting binaries in your system path. On Unix-like systems the binaries are put in either /usr or /usr/local, split into bin and lib. The runtime library is put in /share/kronos/Lib under the prefix. On Windows, the prefix will be an user-specified location in Program Files.
