Does not build on GNU/Linux despite following instructions

[Wuzzy2]

This project does not build for me despite following the instructions in the README file.

I use Arch Linux. These are the installed package versions:

• alsa-lib 1.2.14-2
• freetype2 2.14.1-1
• fftw 3.3.10-7
• mesa 1:25.2.5-1
• libxext 1.3.6-1
• libxrender 0.9.12-1
• libxcursor 1.2.3-1

My build attempt failed after the first step. See the console log below:

libs/drowaudio/meson.build:11:8: ERROR: Include dir ../juce5/source/modules does not exist.

Not sure if I did something wrong, or if it's a problem in the project or build instructions.

the latest git version changed to use submodules, so you need

git submodule update --init --recursive

or clone with --recursive

Yes, this was the missing step, and it works now, thanks. I wasn’t aware that submodules existed.

Please update the README to include this important step.
