[CMake] how to rename file during install ?

[Alexander Neundorf]

Hi, 
 
I have a bunch of icons named like hi16-action-view_fit_height.png. This 
one has to be installed to 
${somePrefix}/16x16/actions/view_fit_height.png .  
 
I have working regexps for the components of the name (size, group, 
actual name) which I can use the determine the target directory, but now 
I'm not sure how to rename the icon during the install step. 
 
INSTALL_FILES() doesn't seem to offer a feature for renaming a file 
during the install step. 
I could add a custom target, which calls  
cmake -E copy <origname> <targetname> .  
 
But how can I add this to the install target ? 
Is there a way to add "directory-recursive" targets ? 
(like "install" or "all": if I "make install" in the root dir, it 
recurses through all subdirs calling "make install" in each of them). 
Having a way to do this for custom targets would be nice :-) 
Any ideas ? 
 
Bye 
Alex
