In case it helps, for compiling babl gegl & gimp i use,

export PREFIX=$HOME/opt
export LD_LIBRARY_PATH=${PREFIX}/lib
export PKG_CONFIG_PATH=${PREFIX}/lib/pkgconfig/
export PATH=$PREFIX/bin:$PATH
export XDG_DATA_DIRS="$PREFIX/share:$XDG_DATA_DIRS"
export GI_TYPELIB_PATH="${PREFIX}/lib/girepository-
1.0:${PREFIX}/lib/${arch}/girepository-1.0:$GI_TYPELIB_PATH"

# enable sqrt() in TinyScheme:
export USE_MATH=1

# https://wiki.gimp.org/wiki/Hacking:Building

and then in each of babl, gegl, gimp in turn,
git pull
rm -rf obj-x86_64/; SRC_DIR=$(pwd); BUILD_DIR=${SRC_DIR}/obj-$(arch);
mkdir -p $BUILD_DIR && cd $BUILD_DIR && meson -Dprefix=$PREFIX -
Dworkshop=true -Dcairo=enabled -Dumfpack=enabled -Dopenexr=enabled 
$SRC_DIR && ninja && ninja install


This assumes you have graphviz, and that you have libmypaint 1.
installed in the same $PREFIX
