From what I understood, the first variable should have solved the problem.
I set -DCMAKE_VERBOSE_MAKEFILE=ON and compiled ktouch. When running it, it
stops with
ktouch: error while loading shared libraries: libkdeclarative.so.5: cannot open
shared object file: No such file or directory
And indeed:
$ ldd ~/.guix-profile/bin/ktouch
linux-vdso.so.1 (0x00007fff961ff000)
libkdeclarative.so.5 => not found
...
(lots of other "not found").
$ objdump -x ~/.guix-profile/bin/ktouch
...

(Thanks to Ludovic for the suggestion to use objdump!)
The linker line looks like this:

-Wl,-rpath,:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
You see lots of "...so" and no "-l...", which is apparently the cmake way of
doing things. But no "-Wl,-rpath" despite
-DCMAKE_INSTALL_RPATH_USE_LINK_PATH=TRUE
Does this mean that this option only honours paths coming from "-l", while
at the same time using "-l" is unusual with cmake?
