Not I don't think so.
I think what you were looking for was some kind of recursive evaluation
like TCL 'eval' command (http://wiki.tcl.tk/1017)
With CMake:
1) you can ask CMake for "double" evaluation
using nested dollar ($) var value:
Try:
set(COMP1_CFLAGS "Whatever")
set(COMP2_CFLAGS "OrElse")
set(COMPILER "COMP1")
set(CFLAGS ${${COMPILER}_CFLAGS})
message("CFLAGS=${CFLAGS}")
2) You can "emulate" function call evaluation using include
this is awkward but seems to work, see example attached.
That said adding a eval command to CMake could be fun,
even if I did never cross the urgent need for it.
