If the problem is that qtbase-5 is propagating a different mesa than the
one we can install (i.e. a different /gnu/store entry), let's try
installing qtbase-5 and using its propagated mesa instead of installing
mesa ourselves.
#+begin_src sh
guix shell geant4-vis cmake make gcc-toolchain qtbase@5
#+end_src
Alas, we still have 2 different mesa versions:
#+begin_example
CMake Warning at CMakeLists.txt:35 (add_executable):
Cannot generate a safe runtime search path for target exampleA1 because
files in some directories may conflict with libraries in implicit
directories:
runtime library [libEGL.so.1] in
/gnu/store/6imr8p8j0d59s4r0912xy8mficw8kc2y-profile/lib may be hidden by
files in:
/gnu/store/2rzdlwb0f7ksj7a78kjn7a7qs22avi8l-mesa-23.3.2/lib
runtime library [libGL.so.1] in
/gnu/store/6imr8p8j0d59s4r0912xy8mficw8kc2y-profile/lib may be hidden by
files in:
/gnu/store/2rzdlwb0f7ksj7a78kjn7a7qs22avi8l-mesa-23.3.2/lib
Some of these libraries may not be found correctly.
#+end_example
The installed qtbase-5 propagates the same mesa as the one we can install:
/gnu/store/6imr8p8j0d59s4r0912xy8mficw8kc2y-profile/lib/libEGL.so ->
/gnu/store/clnk1arbkc6v21a93gxnirvsbjaz5v07-mesa-23.3.2/lib/libEGL.so
So then, where is this other mesa coming from (2rzdlwb...), if not qtbase-5?
I've included possibly relevant lines from the generated CMakeCache.txt
#+begin_example
//Path to a file.
OPENGL_EGL_INCLUDE_DIR:PATH=/gnu/store/6imr8p8j0d59s4r0912xy8mficw8kc2y-profile/
include

OPENGL_INCLUDE_DIR:PATH=/gnu/store/2rzdlwb0f7ksj7a78kjn7a7qs22avi8l-mesa-23.3.2/
include

OPENGL_egl_LIBRARY:FILEPATH=/gnu/store/6imr8p8j0d59s4r0912xy8mficw8kc2y-profile/
lib/libEGL.so
//Path to a library.
OPENGL_gl_LIBRARY:FILEPATH=/gnu/store/2rzdlwb0f7ksj7a78kjn7a7qs22avi8l-mesa-23.3
.2/lib/libGL.so
#+end_example

Happy to report a fix for this: Install both geant4-vis and mesa with the
--no-grafts option. This makes sure only 1 variant of mesa is used.
E.g.
#+begin_src sh
guix shell geant4-vis cmake make gcc-toolchain mesa --no-grafts
#+end_src
Cheers
Jake
