Building Bespokesynth on RPi 400

Building Bespokesynth

# Clone repo
git clone https://github.com/awwbees/BespokeSynth.git

cd BespokeSynth/Builds/LinuxMakefile

make CXX=g++ -j4

# May need extra dependencies installing on the RPi
# The linux Makefile generated by Juce doesn't necessarily work out of the box
# ...there seems to be misconfigured paths for including the OpenGL stuff - get errors like 'GL_RGB was not declared in this scope' when it tries to build the HelpDisplay stuff
# Tried changing the path in the Makefile for libs to /usr/lib, but did not work

Edit Makefile and add `-latomic` to the linker flags, e.g.

```Make
JUCE_LDFLAGS += $(TARGET_ARCH) -L$(JUCE_BINDIR) -L$(JUCE_LIBDIR) $(shell pkg-config --libs freetype2) -fvisibility=hidden -lrt -ldl -lpthread -latomic $(LDFLAGS)
```

# rebuild
make clean
make CXX=g++ -j4
