Not that much simpler than the following example.

Is it really simpler than writing your own simple (or complicated)
script once and launching:
cmake -DINFILE=blah.in -DOUTFILE=blah.out -Dvar1=value1 -Dvar2=value2
-DCOPYONLY=1 -P GenericConfigureFile.cmake
this command may be launched in add_custom_command and you can spare the first
configure_file if you pass all the value you need with -D on the command line.
One option that could be nice would be a way to inherit CMake-time
defined values
at Build-time in order to spare much of "-Dvar1=value1" argument.
Something like a new CMake command that would dump in a file the definition
of the currently defined vars
variables_save(FILE ${CMAKE_CURRENT_BINARY_DIR}/myvarset.cmake)
then you would be able to do
variables_load(FILE /path/to/myvarset.cmake)
and get the previously saved vars defintions.
May be variables_save could take a list of vars as argument:
variables_save(VARS MyVar1 MyVar2 FILE ${CMAKE_CURRENT_BINARY_DIR}/myset.cmake)
I think this should even be doable as CMake macro.
variables_load may simply be
include(/path/to/myvarset.cmake)
