ERROR: Missing prebuilt package for 'libui/0.4.1@bincrafters/stable'
Try to build from sources with '--build=libui'
Use 'conan search <reference> --table table.html'
Or read 'http://docs.conan.io/en/latest/faq/troubleshooting.html#error-missing-prebuilt-package'

I mean is this related to the bintray being turned off? - Or am I misusing it?

Related: running with conan install --build='libui' .. worked, but I'm not sure what find_package is meant to look like…

Folded it all into one CMakeLists.txt, and then ran cmake -DCMAKE_BUILD_TYPE=Debug referring to it:

you need to use the cmake_find_package_multi instead of cmake_find_package when invoking conan_cmake_configure
For more information read https://docs.conan.io/en/latest/reference/generators/cmake_find_package.html and https://docs.conan.io/en/latest/reference/generators/cmake_find_package_multi.html#generated-files
