[Wayne Stambaugh <stambaughw@xxxxxxxxx>]

Congratulations on everyone who made the is happen.  This is a nice
feature for KiCad and hopefully users will find it useful.

There are a few things will need to addressed that I missed when I
initially evaluated the code.

Maybe I missed it but I do not see any indication that the ngspice
headers and libraries are detected during cmake configuration (see
attachment).  This is a major no-no.  All external dependencies must be
found during configuration.  As a developer, there are few things that
make kick a software package to the curb faster than getting 3/4 of way
through a 30+ minute build only have the build fail because there is a
missing dependency header or library.  This should fail during
configuration to inform the developer that there are missing
dependencies.  Please write a FindNgSpice.cmake file.  I know I've said
this in the past but I will reiterate it, if you add a new dependency to
KiCad you *must* add the configuration code to ensure that all of the
required headers and/or libraries can be found before a valid
configuration can be completed.

Also, please update the Documentation/development/compiling.md file with
the added optional ng-spice dependency.  This is the official compiling
document that gets pushed to the kicad website so it needs to be kept up
to date.

Thanks again everyone for your hard work.

Cheers,

Wayne
