Missing icons in GIMP 2.10 custom compilation

[Ofnuts]

It was quite long-winded at the beginning.

Since I can run several Gimp versions in parallel my development structure for a given version looks like this:

Code:

/Gimp-dev/2.10.34
├── build
│   ├── babl
│   ├── gegl
│   ├── gimp
│   ├── GIMP-Lensfun
│   ├── GMIC-3.1.6
│   ├── libmypaint
│   ├── mypaint-brushes
│   ├── pango-1.47.0
│   └── resynthesizer
├── extra
└── run
   ├── bin
   ├── etc
   ├── include
   ├── lib
   ├── libexec
   └── share

• the root (/Gimp-dev/2.10.34 here) contains a script that is sourced to set up the proper environment
  
• build holds the source directories (git pull from repos for babl/gegl/gimp, tarballs for others)
  
• as you can see Gimp added a requirement for a recent version of pango so I had to add it to the mix.
  
• the "prefix" points to the run directory
  
• after a successful build the products are installed under run (so for instance the Gimp executable ends up as /Gimp-dev/2.10.34/run/bin/gimp-2.10.
  
• I start Gimp through a script that sets up the proper PATH/LD_LIBRAY_PATH/GI_TYPELIB_PATH and Gimp profile directory
