[CMake] Custom build step

[pepone.onrez]

Hello i creating a CMake macro for compile same IDL files.

Here is steps i trying to do

1) find all files in  ./slice directory that's end with .ice

for each .ice files

1.1) run slice2cpp compiler that's generate a .h and .cpp file white the
same name as the .ice
1.2) move the .h file to the include directory
1.3) move the .cpp file to the source directory

2) Compile the generated files in a shared library

Here is the macro i use for steps (1.1 1.2 1.3) - the problem is that the
second CUSTOM_COMMAND that's move generated files
to is final destination is not called. Any help is appreciated , thanks in
advance
