Thanks. Trying option 3 (putting everything in one bin/ directory)
seems to work, but I find the changes a bit messy:
https://github.com/libsigcplusplus/libsigcplusplus/pull/31

Option 1 (changing the PATH) seems to be the simplest and most correct
way to do it, but I haven't found quite the correct CMake incantation:
https://github.com/libsigcplusplus/libsigcplusplus/pull/32

If you have a Windows system, maybe you could checkout out that branch
and try it out, please.
