error in archlinux 64bit build
when trying to build the following compilation error is received
HackRF_Streaming.cpp :(. Text + 0x1c4b): undefined reference to 'pthread_cond_clockwait ' /usr/bin/ld: HackRF_Streaming.cpp :(. text + 0x1d25): undefined reference to 'pthread_cond_clockwait ' collect2: error: ld returned exit status 1 make [2]: *** [CMakeFiles/HackRFSupport.dir/build.make: 166: libHackRFSupport.so] Error 1 make [1]: *** [CMakeFiles/Makefile2: 96: CMakeFiles/HackRFSupport.dir/all] Error 2
I solved it by editing lines 41 and 43 of CMakeLists.txt adding -lpthread
but surely this is not the best way to do it.
Its the second time I have seen that error. Maybe a new compiler feature or pthread update. I think I might make SoapySDR itself add -lptread in general to the modules to prevent this going forward
For what it's worth, I'm using up to date Arch Linux on amd64 and building from source is working perfectly here, in addition to the "soapyhackrf" package and "soapyhackrf-git" PKGBUILD in AUR.

A few weeks ago it was built perfectly, but yesterday when I built it again it failed in AUR, so I decided to take a look. Searching I realized that it is a recent error and not very common so I decided to report it here.
