Also, be sure to create a test_v1_package test package and update the test_package to use the new Conan CMake generators. Thanks!

Looking really good. I think all that's left besides the couple of small tweaks is to use the new CMake generators in the test_package. Nvm, I see you just updated the test_package. That looks great.

This doesn't work, and results in the error

ERROR: gdk-pixbuf/2.42.9: Error in validate() method, line 64
        if self.info.options["glib"].shared and microsoft.is_msvc_static_runtime(self):
        ConanException: option 'shared' doesn't exist

I don't entirely follow the explanation of the difference between self.info.options and self.options, but I assume it is to do with the latter being the options of a dependency

In the validate method, you should use the dependencies model to access the options of glib. I think something pretty close to the following should work.

Can you remove the test_v1_package/test_package.c file now that it's using the test_package/test_package.c file?
