CCD/CMOS imaging server
=======================

Supports FLI cameras/focusers/wheels and ZWO cameras.
Allows to run as standalone application or imaging server/client.

To restart server (e.g. if hardware was off) kill it with SIGUSR1

## Compile

cmake options:

- `-DDEBUG=yes` -- make with a lot debugging info 
- `-DIMAGEVIEW=yes -- compile with image viewer support (only for standalone) (OpenGL!!!)
- `-DZWO=yes` -- compile ZWO support plugin
- `-DFLI=yes` -- compile FLI support plugin



```
