You can't point to the module inside GNU Radio, because that might not be installed when you're developing a module. If your way works, that's great, but maybe this can be factored out into a single CMake module as not to bloat the individual CMakeLists.txt files. Cheers, Martin On 03/24/2016 0

The short answer is, the templated in-tree stuff has access to some modules we don't actually export to OOTs. You'll need to copy the template infrastructure into your OOT. Cheers, Martin On 03/24/2016 11:25 AM, Jacob Gilbert wrote: > I am attempting to add several templatized blocks to an OOT mo
