Apparently there is an issue when you try to compile under OSX.
Problem occurs when QT4 is installed and collides with QT5 while running Cmake.
I have been able to solve this issue simply by running:
CMAKE_PREFIX_PATH=$(brew --prefix qt5)/lib/cmake cmake .. -DCMAKE_CXX_FLAGS:STRING=-I/usr/local/opt/qt5/include ..
I recommend adding this to readme.md.
I've wasted quite some time trying to find a workaround for this... And your solution actually works, thank you a lot!. GQRX and USRP b200 mini also compile well with this fix.
fixes the qt5 issues reported in #40 and #60
Fixed in #87
