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.
