I think this may have been a bug in CMake 2.2.  It will be fixed in 
2.4.2, but I'm not sure if it was already done in 2.4.1.

Any other approach will require some CMake fixes.  Once it is 
implemented properly you could do something like

SET(NRC206_SRCS ADDINT.C ...)
SET_SOURCE_FILES_PROPERITES(${NRC206_SRCS} PROPERTIES COMPILE_LANGUAGE C)
ADD_LIBRARY(NRC206 ${NRC206_SRCS})

to override the default choice of compile language for capital ".C" 
extensions.  I'm not sure when we'll get to this.
