You add it to this line in lib/CMakeLists.txt:
target_link_libraries(gnuradio-xxx ${Boost_LIBRARIES}
${GNURADIO_ALL_LIBRARIES})
like so:
target_link_libraries(gnuradio-xxx ${Boost_LIBRARIES}
${GNURADIO_ALL_LIBRARIES} -lgsl)
This is the quick and dirty way. The better way is to use a cmake
find_package command.
In ./CMakeLists.txt after these lines:
find_package(CppUnit)
find_package(Doxygen)
add:
find_package(GSL)
This is optional, but I like to add it. After this line:
if(NOT CPPUNIT_FOUND)
message(FATAL_ERROR "CppUnit required to compile xxx")
endif()
add:
if(NOT GSL_FOUND)
message(FATAL_ERROR "Gsl required to compile xxx")
endif()
In lib/CMakeLists.txt:
target_link_libraries(gnuradio-xxx ${Boost_LIBRARIES}
${GNURADIO_ALL_LIBRARIES} ${GSL_LIBRARIES})
Finally, copy the file gnuradio/cmake/Modules/FindGSL.cmake to
your OOT cmake/Modules. You may want to edit out all the Windows
stuff in it (assuming you're on Linux).

Dear GnuRadio experts,
I want to use some minimization functions from the Gnu
Scientific Library (GSL) in my own OOT module, e.g. a simple
1-D minimizer such as Brent’s method. In my OOT module I can
compile and install my new block with GSL without any errors
(seems like compilation and linking worked), but when the
flow-graph in GRC is started I get an error that a module
(which is already there and worked before) cannot be found. I
had a similar problem once when I used e.g., the FFT block in
my OOT module and forgot to add “FFT” as part of the required
blocks in the CmakeLists file. There I got the some error
message.
So how do I add the GSL correctly to my Cmake list? I checked
some older mails in the archive but did not get any smarter. I
also saw that GnuRadio already depends on GSL. So how could I
proceed?
Regards,
Emanuel
