You are right. I was confusing cmake time with build time.  However, what is
to stop you building your own version of wxwidgets as an external project?
Then cmake; make, etc., would have to be run once to build wxwidgets and
once for your project.  If that turned out to be too complicated for your
users, you could put those commands in one overall script to simplify their
builds.

I believe you misunderstood.  We only want to use the wxwidgets compile
flags and link flags on a (extremely small) subset of our source files and
targets.  So we have to use the appropriate CMake commands to set that up.
It sounds like you may not have that requirement.
