Re: wxWidgets 3.2.2.1: Does configure install wxWidgetsConfig.cmake?

There is https://github.com/wxWidgets/wxWidgets/issues/22714 that 
addresses the issue of different files being installed.
I haven't looked into it yet.

wxWidgetsConfig.cmake is not a stand-alone file. It relies on 
wxWidgetsTargets.cmake.
These target files are generated by CMake, and contain compile 
definitions, include directories, link dependencies and library paths 
and names for each library.

You can just generate them, add them to the repo, and include them in 
the installers.
Different configure options (like shared or static) will result in 
different library names.
And link dependencies (paths/names) could be different for different 
distros.
So you'll need some script that generates the config and target file(s), 
and fills them with the stuff from configure.
Which seems not at all trivial.

To solve your initial problem.
If wxWidgets is installed with configure, you can use 
find_package(wxWidgets) 
(https://cmake.org/cmake/help/latest/module/FindwxWidgets.html) (without 
CONFIG).
This use wx-config internally. Your configure install should have 
installed this wx-config.
So I think if /path/to/somewhere/bin is in your path, it should find and 
use that wx-config, and CMake will be able to find that wxWidgets 
installation.
Setting a WX_CONFIG env. var. is also possible.
