Where do I find LIB environment variable?

[Ptolemy]

I'm following the instructions for installing KD SOAP. In step 4 the instructions says:

bq. Add the path to KD SOAP lib into your LIB environment variable and the path
to KD SOAP bin into your PATH environment variable.

So where do I find the LIB environment variable?

I couldn't find it in the list of envorinment variables, like i did with the PATH variable.

When setting the PATH environment variable i did it here:
@Computer (right click)->Properties->Advanced system settings->Advanced->Environment variables.@

So I figure that also the LIB environment variable was here. So where can i find it?

You create it (although I am not sure what uses it)

Yes, you can create it if it doesn't exist. or simply run

@
set PATH=thebinpath;%PATH%
set LIB=thelibpath;%LIB%
@

in your working CMD window.
