Hi, I've been working on the JOIN genex in my join-genex branch and encountered some generic issues along the way relating to use of lists with generator expressions. I don't propose merging the JOIN feature for the next release, but there seems to be remaining issues which would be best solved in 2.8.11.
I think at some point, we wanted to be able to use lists in the arguments of generator expressions, such as. I added cmGeneratorExpression::Split in f99196dc0cde6e5868cc74c603a78b10f1ba324a and used it in a3aedb8152ad6fcdb42fd04e45307eea6ce0043e so that targets in $<1:foo_target;bar_target> could be extracted. For the JOIN genex to be useful, I'll need to be able to handle lists there too. I'm hitting problems of conflicting requirements though, when used with add_custom_command, and I'm not certain what to about them. One solution to the class of problem I'm come up against as it relates specifically to the Qt 4 macros is to always write to the parameters file, not only on Windows. That at least hides the argument list from add_custom_command. That is not a generic solution though. Any comments on this stuff?
