[swift-dev] build error: INSTALL cannot find readline.so

[Todd Fiala]

I think that bug has details in it, but specifically I think you need to delete just the lldb and maybe the llbuild (?) build directories.  This should cut down the (painful) rebuild time.

This looks to be some kind of known deficiency in the cmake/ninja generator handling.  We found links to other projects hitting this as well.

I have only been able to reproduce this by restarting a build after some previous failure.  The workaround (for me at least) is to delete the build directory and restart from the beginning (not ideal to be sure).
