Homebrew Need help compiling the ctrQuake hardware rendering branch

[Wavy]

I found out that ctrQuake has a hardware rendering branch here. I tried to compile it but it gave me an error relating to how it can't find a gl.h header file. But all I needed was to install a library from the same creator called picaGL (which you can get here) in my devkitPro directory. I tried to make ctrQuake again but it threw a lot of warnings/notes at me then after that it was linking to "ctrQuake.elf" it gave me this:

linking ctrQuake.elf

make[1]: *** [/opt/devkitpro/devkitARM/3ds_rules:42: /home/devkitpro/ctrQuake/ctrQuake.elf] Error 1
make: *** [Makefile:182: build] Error 2

Just for some info, I'm running this in Ubuntu under WSL. So any help on compiling this would be nice! If you need more info, tell me
