CyanogenMod 12.1
Official nightlies started and there's a thread for it, check it out: Link
I'll no longer update this project, my focus is now at CyanogenMod 13 (CM13 thread link)

Samsung Galaxy SII

CyanogenMod 12.1

CyanogenMod is based on the Android Open Source Project with extra contributions from many people within the Android community. 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 Github Repo.

Code:
#include 
/*
 * Your warranty is now void.
 *
 * I am not responsible for bricked devices, dead SD cards,
 * thermonuclear war, or you getting fired because the alarm app failed. Please
 * do some research if you have any concerns about features included in this ROM
 * before flashing it! YOU are choosing to make these modifications, and if
 * you point the finger at me for messing up your device, I will laugh at you.
 *
 * Submitting bug reports on unofficial builds is the leading 
 * cause of male impotence.

F.A.Q


Q. Can i install CM12 over CM11 without wiping data?
A. This is not recommended, you have to wipe everything to upgrade from CM11 to CM12

Q. What recovery does this ROM support?
A. You can use Kitkat Compatible CWM recovery to flash it (6.0.4.5+). Also, we'll integrate CWM 6.0.5.1 in future builds as a permanent solution.

Q. Which GAPPS package should i install?
A. You can install "NANO GAPPS" if you haven't re-partitioned your system OR you have stock System Partition size.

Q. How much System Partition size is needed to flash this ROM?
A. you can flash this ROM on your stock system partition but it is recommended to have 1GB System Partition as ART runtime requires more space. also, it's advisable to have more space on system partition if you would like to install standard GAPPS package.

Q. How can I increase System Partition space?
A. You will need to flash PIT file in ODIN or heimdal to re-partition the System space, it is recommended to have 1GB System Partition as ART runtime requires more space. for more details about PIT files & re-partitioning click here : http://forum.xda-developers.com/gala...y-app-t2538947 and here: http://forum.xda-developers.com/gala...-size-t3011162
another PIT files are here : http://forum.xda-developers.com/show...&postcount=509

Q. I didn't like the ROM or I want go back to stock ROM or this ROM didn't worked & want to revert back, how can I?
A. Yes, you can revert back to Stock ROM or any other ROM, you can wipe everything & flash the ROM of your choice whether it's stock or AOSP based ROM. Please follow this steps to revert back to your ROM (these steps are for total noob users)
1 - Go to recovery mode
2 - Make sure that your recovery is compatible with Kitkat if you are flashing a ROM based on Kitkat. If not then flash a Kitkat compatible recovery (as mentioned above).
3 - Flash your ROM.

Q. Can I flash another kernel after flasing this ROM?
A. Yes, of course you can flash kernel of your choice, just reboot to recovery & flash the zip.

Q. I guess I have soft bricked the device, what should i do now?
A. Follow the guide here : http://forum.xda-developers.com/gala...-gsii-t1457458

Q. Can I apply another theme on this ROM?
A.Yes, you can search for CM12 themes on xda or on the Play Store, install it and apply the theme from the Themes section on Settings.

Thanks to @c0d3r!pp3r for the FAQ

I'm pretty sure that CM don't have a theme engine on 5.0, also, you don't want to apply a theme on a unstable rom.

As stated on OP you need a Kitkat Compatible CWM recovery to flash it (6.0.4.5+)
Updated OP with gapps ( I did not test the ROM with gapps )
