[QBS] Preserve directory structure during installation

[Richard Weickelt]

Hi,

how can I install a specific file type from a given folder while preserving
the folder hierarchy?

Example:

source-dir
|
+-- subdir1
|   +--file1.h
|   +--file1.cpp
|
+-- file2.h
+-- file2.cpp

should install to:

install-root
|
+-- include
    |
    +-- subdir1
    |   +--file1.h
    |
    +-- file2.h

The following snippet

Group {
  prefix: "**/"
  files : "*.h"
  qbs.install : true
  qbs.installDir : "include"
}

would just gather all .h files and copy them to 'include'. Creating a group
for every folder would be possible, but is cumbersome when it comes to large
folder hierarchies. Is there any generic solution for that?
