the goal here to mark functions and variables not used outside the
translation unit as static. main reason for this is cleanliness. however
as a side-effect this can help compilers optimize better as it now has
guarantee that a certain function won't be called outside of that
translation unit.
one other side-effect of this is that accessing these vars/function from
config.h is now different.
if one wants to access a static var/func from different translation unit
in config.h, he would have to create a wrapper function under the right
ifdef. for static functions one would also need to forward declare it.
here's a dummy example of accessing the function `run_key_handler` from
config.h under _MAPPINGS_CONFIG
```
static void run_key_handler(const char *, unsigned);
bool send_with_ctrl(arg_t key) {
run_key_handler(XKeysymToString(key), ControlMask);
return false;
}
```

Dependencies
nsxiv requires the following software to be installed:
- Imlib2
- X11
The following dependencies are optional.
- inotify : Used for auto-reloading images on change.
Disabled via
HAVE_INOTIFY=0 - libXft, freetype2, fontconfig : Used for the status bar.
Disabled via
HAVE_LIBFONTS=0 - giflib : Used for animated gif playback.

Please make sure to install the corresponding development packages in case that you want to build nsxiv on a distribution with separate runtime and development packages (e.g. *-dev on Debian).
Building
nsxiv is built using the commands:
$ make
You can pass HAVE_X=0 to make to disable an optional dependency.
For example:
$ make HAVE_LIBEXIF=0
will disable libexif support. Alternatively they can be disabled via editing
the Makefile directly. OPT_DEP_DEFAULT=0 can be used to disable all
optional dependencies.
Installing nsxiv:
# make install
Installing desktop entry:
# make install-desktop
Installing icons:
# make install-icon
Installing all of the above:
# make install-all
Please note, that these requires root privileges.
By default, nsxiv is installed using the prefix /usr/local, so the full path
of the executable will be /usr/local/bin/nsxiv, the .desktop entry will be
/usr/local/share/applications/nsxiv.desktop and the icon path will be
/usr/local/share/icons/hicolor/{size}/apps/nsxiv.png.
You can install nsxiv into a directory of your choice by changing this command to:
$ make PREFIX="/your/dir" install
Example scripts are installed using EGPREFIX which defaults to
/usr/local/share/doc/nsxiv/examples. You can change EGPREFIX the same way
you can change PREFIX shown above.
The build-time specific settings of nsxiv can be found in the file config.h. Please check and change them, so that they fit your needs. If the file config.h does not already exist, then you have to create it with the following command:
$ make config.h
