[SOLVED] Unable to remove Dolphin when built from source (Linux)

[Reboot]

Hello all,

I'm trying to diagnose a problem which involves controller input (here), and I'm trying a bunch of different things to try and solve this. Now I have installed Dolphin from source (with this guide), but of course there is nothing different as it is the same version you would get with apt-get.
However, I'm currently stuck with this version of Dolphin because there is no way to remove this with make. (make: *** No rule to make target 'uninstall'. Stop.). Of course apt-get can't clear this out of the way because it is not recognized as a installed package retrieved from the internet. So my question is:

How can I remove Dolphin when built from source?

P.S. I am able to install dolphin-emu-master (apt-get) but I won't be able to launch it. (command not found [when installed of course]

[Reboot]

NEVER MIND. There is a readme.md file with instructions that I haven't read. I'm smart.

HOWEVER: As stated from the readme:
Linux users can run `cat install_manifest.txt | xargs -d '\n' rm` as root from the build directory
to uninstall Dolphin from their system.

install_manifest.txt does not exist in my build directory. Help please?

Ech. I'm smart. there is a 'Build' directory in the directory I used to compile Dolphin in. Never mind again.
Notes for other users wishing to remove Dolphin (compiled from source):
You will need root access for this, and sudo does not work. To gain root access, do
sudo -i
then browse to the Build directory again
cd /home/USERNAME/PATH/"TO THE"/SOURCE/Build
and then run cat install_manifest.txt | xargs -d '\n' rm

Remember to exit the terminal properly as your computer is vulnerable when left in root mode
