If you really wanted to pass the name of the variable in rather than the
value, then as Rolf says the behaviour you get is as expected. The only way
round that would be to rename var in the function to something guaranteed
not to be the name of a variable that you ever tried to pass in.
Or you could use a macro instead:
MACRO(buildm var)
MESSAGE(STATUS "var: " ${${var}})
ENDMACRO()
SET(var red blue yellow green)
buildm(var)
-- var: redblueyellowgreen
