file-api: export projects generated by ExternalProject_Add
At include project files from cmake ExternalProjects I have a feature request that would be better served by CMake itself.
In a cmake project with several projects added by ExternalProject_Add(), none of the sources of the added external projects are shown in the Project browser.
The individual cmake projects can be loaded successfully.
Would be much more convenient to be able to edit the sources of the external projects in the context of the 'super' project that adds them as external projects.
For the external project that are built using CMake it shouldn't be that hard to have such a functionality available. The external projects would be configured with the same query arguments as the main project and the main project would get the external projects referenced somehow in the main project.
