So, for example, I open a .SLN file generated by CMake, look in the "Solution Explorer" pane of Visual Studio 2008, and see the infamous ALL_BUILD in the list between two of my projects. (I haven't opened any of these projects yet, so the entire list is at one level of indentation below the "Solution" icon.) ALL_BUILD shows up in this list because there's a file ALL_BUILD.vcproj in the same directory as my .SLN file in the filesystem. And there are no .CPP files that are built by ALL_BUILD itself (though of course ALL_BUILD depends on projects that do build .CPP files). I tend to call ALL_BUILD a "project" because it shows up at the same level of the hierarchy as all the projects in Solution Explorer and because the "proj" in the filename ALL_BUILD.vcproj suggests the word "project" to me. But I suppose technically I should call it a "target". Anyway, I'm pretty sure now I completely misread the earlier email. Not so sure I read it correctly this time, though. > I'm hoping source_group() can be used without any project and > simply add solution folders to the solution. Actually this seems counterintuitive to me. There's no other case in which SOURCE_GROUP by itself would cause a .VCPROJ file to be generated. And the icon that shows up in Solution Explorer looks like a little manila file folder (the kind you could buy at a stationery store in 1970, before some genius decided it was a synonym for "filesystem directory"), whereas the icon for a "project" in Solution Explorer looks completely different (but is identical to the icon for ALL_BUILD). I guess one could question why one level of the hierarchy is different from all other levels, but it _is_ different (blame the designers of Visual Studio) and I think it would be too confusing to pretend otherwise. Also, you specifically don't want any source files in the thing you're creating, which seems already to say it's not a "source group". It seems to me that what you want is a command that you can use instead of ADD_LIBRARY or ADD_EXECUTABLE to create a new target. Actually I think there are some such commands; maybe one of them does what you want (but if so, someone else will have to explain it, because I don't know how to use any of those commands). Otherwise, it seems to me you need a new command. David _______________________________________________ CMake mailing list CMake@cmake.org http://www.cmake.org/mailman/listinfo/cmake
