> Please do a "make VERBOSE=1" so we can see the full command. I would guess
that FindLAPACK.cmake sets LAPACK_LIBRARIES simply to "-llapack", instead of
the full path to the library. Have a look at FindLAPACK.cmake and check
whether it uses FIND_LIBRARY() to set LAPACK_LIBRARIES.

Also, please print out ${LAPACK_LIBRARIES} (using

MESSAGE("LAPACK_LIBRARIES = ${LAPACK_LIBRARIES}")

so we know how the lapack cmake module is defining that variable.

The linker should normally be able to use the -llapack option to find the
lapack library on Linux.  Since it doesn't find it, I am wondering if the
lapack library is installed somewhere non-standard where the linker cannot
find it.  What happens if you

export LD_LIBRARY_PATH=/path

where /path is the path to where the lapack library has been installed?
