Of itself, this is not an explanation for a missing cyglz4-1.dll, as it 
is contained in both versions of the package (even if the package 
version has changed, the soversion doesn't change) (compare the package 
contents seen at [1])

[1] https://cygwin.com/packages/x86_64/liblz4_1/

setup thinks liblz4_1 is already installed, so doesn't install it again.

 >> 2017/12/02 14:06:47 Adding required dependency liblz4_1: Selecting 
already-installed version .

This is weird, since it seems to indicate that PrereqChecker::isMet() 
noted it as needing to be installed, but that 
PrereqChecker::selectMissing() thinks it is already installed.
