[CMake] CPack, optional files and windows service

[Bo Thorsen]

Hi everyone,

I'm currently working on creating a windows installer for MariaDB (MySQL 
replacement, see http://www.mariadb.org). It's going quite well, and the 
installer seems to be working. I'm quite amazed at how simple it has 
been so far :)

I have two things I'm working on that are not so easy to do, and I 
haven't found any links online to documentation on how to do this. I 
hope some of you can help me with this or send me the links I couldn't find.

1) I have to make some of the files optional. When uninstalling the 
MariaDB server, it should ask if the user wants to delete the database 
files are keep them. Same on installing, since there might already be 
database files there. I can't figure out how to make CPack ask if it 
should write/delete these files. Putting the files in a separate 
component is not enough - the user has to make the decision conciously. 
Any ideas?

2) The database server should be installed as a Windows service. Again, 
the user should probably be asked about this, but this might be a 
component. Are there any examples on how to register a service using 
cpack, and how to create start menu links for starting and stopping the 
service?

I hope you have some good ideas on how to do this. If you only have some 
of the answer, just give me that and I'll work with it.

Cheers,
