I would think that this is exactly what the string configure command is for:

Is there anyway to do in a generic fashion?
For example, I don't know what all the variables are.
I can be certain that they are valid, for example build-dir is set in scope.
However, the string can have several "variables" in it.
The following function EXPAND() replaces all occurrences of "${...}" in
INPUT with the current value of the appropriate variable and stores the
result in OUTPUT:
FUNCTION(EXPAND OUTPUT INPUT)
STRING(REGEX MATCH "\\\${[^}]*}" m "${INPUT}")
WHILE(m)
STRING(REGEX REPLACE "\\\${(.*)}" "\\1" v "${m}")
STRING(REPLACE "\${${v}}" "${${v}}" INPUT "${INPUT}")
STRING(REGEX MATCH "\\\${[^}]*}" m "${INPUT}")
ENDWHILE()
SET("${OUTPUT}" "${INPUT}" PARENT_SCOPE)
ENDFUNCTION()
So, e.g., set(foo \${build-dir}/foo.c) and expand(foo ${foo})
with build-dir=/tmp/src yield foo=/tmp/src/foo.c as desired.
Regards,
Michael

Sorry for another newbie question.
Say, to setup a variable as follow so ${build-dir} doesn't get expanded
set(foo \${build-dir}/foo.c)
How would a expand foo so ${build-dir} gets expanded?
STRING(REPLACE "\${build-dir}" "xyz" foo "${foo}")
Regards,
Michael
