I tried using this guide but on executing the "make" command, I got the following error :

Code: 
Siddharths-MacBook-Pro:guide.git siddharth$ make
iasl -vw 2095 -vw 2008 -vi -vs -p build/SSDT-ALS0.aml hotpatch/SSDT-ALS0.dsl
error    6092 - Could not open file "build/SSDT-ALS0.pre" (Preprocessor Output) - No such file or directory

make: *** [build/SSDT-ALS0.aml] Error 1

Here's the required Error Reporting logs and the files are attached.

Looks like you probably (mistakenly) removed the build directory (~/Projects/guide.git/build)
The build/readme.txt is there for a reason.
Start over with a fresh copy of the repo.
 
I didn't remove it.. Just to be sure, I deleted the previous copy of the repo and re-cloned it but I still get the same error. The contents of ~/Projects/guide.git/build are in the screenshot attached.

Attach complete ~/Projects/guide.git as ZIP.

I had no problem using 'make' here with that guide.git.
Perhaps you created a case sensitive file system? (note 'Build' vs. 'build').

That's right. I'm using a case sensitive FS. What to do now?

Using case sensitive file system is asking for trouble...

Terminal:
Code: 
cd ~/Projects/guide.git
git mv Build/readme.txt build/readme.txt
make

Okay so that worked and I followed all your steps correctly but the AppleBacklightInjector doesn't seem to load up. Here's the required terminal output and the files are in a zip.
