Looks like this line, inherited from the previous definition, was giving some
trouble:
> (string-append "-DCMAKE_INSTALL_LIBDIR=\\"" (assoc-ref %outputs
> "out") "/lib\\"")
It was creating wrong variables (and wrong syntax too!):
if(EXISTS
"$ENV{DESTDIR}/tmp/guix-build-freecad-mine-0.18.5.drv-0/build/"/gnu/store/30rcpcdv7h6ak37wf30ijlbf9x2j6jyz-freecad-mine-0.18.5/lib"/libSMDS.so"
AND
NOT IS_SYMLINK
"$ENV{DESTDIR}/tmp/guix-build-freecad-mine-0.18.5.drv-0/build/"/gnu/store/30rcpcdv7h6ak37wf30ijlbf9x2j6jyz-freecad-mine-0.18.5/lib"/libSMDS.so")
I think I'll manage to solve this myself.
