-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Jeroen,
it's not advisable to use the 3.7 Out of tree-module directory architecture with GR 3.6. However, gr_modtool should be generating modules that fit exactly your installed version. You shouldn't have to change anything on the gnuradio core/runtime/gruel/whatever includes. After you have set up your new module with gr_modtool, just copy over the original GNU Radio FindFFTWf.cmake into the cmake/Modules directory, and use FindPackage(FFTWf) as well as add the found directories to your target link libraries and the found includes to your include directories; see my reply to Johannes Demel's post of yesterday. Greetings, and happy hacking!
