It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. CyanogenMod does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for CyanogenMod is available in the CyanogenMod https://github.com/CyanogenMod

Installation

Make a backup!

If you were on CM 10.1 or a stock ROM prior to 4.2, upgrade to stock 4.2 first.

Install ClockworkMod recovery with SELinux support. Older CWM will result in a "status 7" error.

Reboot into recovery

If you are using a recovery which mounts /system on boot, unmount it before installing

Wipe data if coming from stock or other ROMs (You may get a "status 7" error if you fail to wipe.)

Install the ROM

Optionally install the Google Apps Addon (In Marshmallow, you MUST flash gapps before booting into the system for the first time or else the proper permissions will not be granted resulting in Setup Wizard crash. If you experience the crash, you will need to do a factory reset.)

To upgrade to a newer build, simply flash the zip. There's no need for data wipe or flashing Google Apps again. (However, if you are experiencing strange issues, you may want to try a wipe.)
