resolves linking issues # with bitcoin-qt.
Can this be more specific? Why is this only needed in Guix? Is it fixed in later versions of Qt?
Guix's cmake-build-system continue to build without issues.
Is this guaranteed? Or just happens to work now by chance / might break in the future?

Otherwise, the build/src/qt/CMakeFiles/bitcoin-qt.dir/link.txt contains -L/home/hebasto/.guix-profile/lib (on my machine), which results in errors noted by @TheCharlatan.
Why is this only needed in Guix?
Because Guix sets it to a value which does not work for us. For more details, please refer to https://mail.gnu.org/archive/html/guix-commits/2015-03/msg00518.html.
Is it fixed in later versions of Qt?
I don't know. Lurking through the https://bugreports.qt.io did not help much.

No guarantees. However, if any package, which uses Guix's cmake-build-system, fails to find its dependencies we still able to specify hint via the CMAKE_LIBRARY_PATH and/or CMAKE_INCLUDE_PATH environment variables.
As an alternative solution, we might consider the patching:

Ok, so this isn't really guix specific then, other than it's currently only been seen in Guix (i.e I assume a problematic -L could appear outside of a Guix build)? Shouldn't this be worked around by patching Qt in depends?
Because Guix sets it to a value which does not work for us.
You mean doesn't work for Qt? I assume the exact same problem would happen to anyone (outside of Guix) setting CMAKE_PREFIX_PATH to a value Qt doesn't like?

Reworked. The CMAKE_PREFIX_PATH environment variable is not touched anymore.

If this is needed, can it be set ealier / in depends and then passed down as part of the configuration? I assume anything built with CMake in depends could have this same problem? Setting this at this point, would make it seem like our depends configuration is leaky. The toolchain file/configuration it produces should not be looking outside of depends for anything?

That was that I considered first. However, CMAKE_FIND_USE_CMAKE_ENVIRONMENT_PATH=OFF disables other facilities the user might be interested in, for example the <PackageName>_DIR variable. And, in other non-controlled by Guix cases, the user is the one who is responsible for the CMAKE_PREFIX_PATH environment variable.
In other words, I think nothing is wrong with our depends. But Guix just overuses the CMAKE_PREFIX_PATH environment variable.

for example the _DIR variable.
Discussed this offline. Usage of <PackageName>_DIR variable. is basically just reintroducing ALLOW_HOST_PACKAGES, which is not something we need to support (in depends).
