I do not rememeber where I found this in the docs, but I did this like 
documented by the cmake guys.
No reference at hands in this minute ...

I do not know the ide stuff here. But when the cmake guys document that in 
this way, I expect that to work also with those ide's cmake supports ...

Ask the cmake guys. What I provided appears to be the documented way to cope 
with this kind of configuration files.

It appears to work at least on my workstation.

Given your previous requirement with duplicated include directories ...
You might notice that when the Config files are listed in the header list, it 
is installed twice by the make install target:

[..]
-- Install configuration: ""
-- Installing: /tmp/xxx/include/osg/Config
-- Installing: /tmp/xxx/include/OpenThreads/Config
[..]
-- Installing: /tmp/xxx/include/OpenThreads/Version
-- Up-to-date: /tmp/xxx/include/OpenThreads/Config
-- Installing: /tmp/xxx/lib64/libosg.so.2.5.3
[..]
-- Installing: /tmp/xxx/include/OpenThreads/Version
-- Up-to-date: /tmp/xxx/include/osg/Config
-- Installing: /tmp/xxx/lib64/libosgDB.so.2.5.3
[..]

Whereas the Up-To-date lines do not happen with what I provided.
You may alternatively remove the INSTALL_FILES directive from my changes to 
get rid of that ...

I am fine with all that works - just want to share what I was digging out when 
doing that ...
