I want to use a generator expression which puts some text on the command-line of compiling certain targets of mine. The thing is, I need different text for CUDA targets and different text for C++ targets; and for reasons, I have to use the same generator expression for all of them.
So, I want write something like $<IF:$<TARGET_LANGUAGE:CUDA>,foo,bar> - except there is no such thing as TARGET_LANGUAGE.
Here is the list of target-dependent generator expression kinds; I've reproduced it below. I don't see something I could use for the language. What can I do?

TARGET_NAME_IF_EXISTS
TARGET_NAME
TARGET_PROPERTY
TARGET_OBJECTS
TARGET_POLICY
TARGET_FILE
