RHEL 8 HPC cluster meson.build version 1.2.0: ariable 'dep_llvm' in the subproject 'subprojects/llvm' is not found

[LinuxPersonEC]

I created a subprojects directory with a llvm.wrap file containing:

[wrap-git]
url=https://gitlab.gnome.org/GNOME/glib.git
revision=glib-2-62
depth=1

[provide]
glib-2.0=glib_dep
gobject-2.0=gobject_dep
gio-2.0=gio_dep
Which gets me further but still ends with:
llvm| Subproject llvm finished.

using ~/.local/bin/meson setup -Dllvm=enabled -Dgallium-drivers=swrast -Dvulkan-drivers=swrast -Dshared-llvm=disabled -Dcmake_prefix_path=/burg/opt/llvm/16.0.6/bin --native-file custom-llvm.ini

WARNING: Variable 'dep_llvm' in the subproject 'subprojects/llvm' is not found
Dependency llvm (modules: bitwriter, engine, mcdisassembler, mcjit, core, executionengine, scalaropts, transformutils, instcombine, native) from subproject subprojects/llvm found: NO

../meson.build:1680:13: ERROR: Dependency 'llvm (modules: bitwriter, engine, mcdisassembler, mcjit, core, executionengine, scalaropts, transformutils, instcombine, native)' is required but not found.

Without the wrap file I got:

Anything obvious here that I'm missing?
