Hi Martin, I did look through the CMake documentation and was trying different things with the target_link_libraries tag, with no success.
What I am trying to do is (and this may be a solved problem already) build a gnuradio block for the RFSpaces SDR-IQ receiver. This is mostly for me to become more familiar with Linux programming and to learn more about Python. I wrote a library that is able to retrieve data from the SDR-IQ and it is called libsdriq.a, now I want to use that library with gnuradio. Following the gnuradio tutorial on out of tree blocks, I created a block called gr-sdriq and it works fine with dummy data, has a complex output port and outputs a cosine and sine to the real and imaginary parts and I can see the data as expected in gnuradio. My problem is getting the gnuradio block to use my libsdriq.a library and that is where things are breaking. Compiling is not a problem, but linking is not producing a gnuradio block that includes my libsdriq.a. I've looked through some gnuradio blocks to see if I could find something similar and through CMake documentation. This is likely solved through CMake, but haven't figured it out yet.
