I've read that before but didn't find anything new there. I also tried
checking the state of BOOTSTRAP_WXWIDGETS and the target separately and
both individually seem to test correctly.

It seems the problem is:
if(BOOTSTRAP_WXWIDGETS AND NOT TARGET wxWidgets)

though I don't see anything semantically wrong with it.


Also search for 'cmake superbuild' for discussion of how people are using

Very interesting but not quite what I'm looking for, in this case the main
CMakeLists.txt does actually build a project, I just need it to build
wxWidgets first.

Thanks,
