I want to distribute executables and libraries of a C/C++ project on Linux, OSX and Windows. What are the preferred CPack generators, i.e. which are likely to be available for most users? On Windows there only seems to be NSIS, but on Linux and OSX there are several alternatives. By the way, a source distribution is generated as well, so in theory, users of all platforms should be able to compile the code themselves, but we want to provide precompiled binaries for convenience.
