I believe you need the target as the first arg to target_link_libraries...I
didn't test this but sure sounds like what the error is saying...
target_link_libraries (wsprd ${FFTW3_LIBRARIES})

Subject: [wsjt-devel] Help with CMakeLists.txt ?
Hi all,
Perhaps someone can help me to properly tweak CMakeLists.txt in the
wsjtx_exp branch so that the WSPR decoder wsprd[.exe] can be built by cmake
along with the other v1.6 executables.
Up to now I've been building wsprd manually, using one of the makefiles in
.../wsjtx_exp/lib/wsprd. It's a trivial compile, using gcc or clang on the
files wsprd.c wsprd_utils.c fano.c tab.c nhash.c and linking the result
against the "double" version of FFTW3, libfftw3-3.dll.
Here's what I did to CMakeLists.txt:

What needs to be done so that the double-precision FFTW library is
accessible for linking to wsprd?
(In passing, I'll mention that this need may be temporary -- I might change
to using the single-precision FFTW routines, as elsewhere in WSJT-X. But
for now, I've built wsprd with the "double" FFTs.
Thanks for any help!
