The make process (make) (make_protocol.log) ends with an error:

ld: symbol(s) not found for architecture x86_64
collect2: error: ld returned 1 exit status
make[2]: *** [bin/jpscore] Error 1
make[1]: *** [CMakeFiles/jpscore.dir/all] Error 2
make: *** [all] Error 2

It compiles with

cmake 
-DCMAKE_CXX_COMPILER=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++ 
-DCMAKE_BUILD_TYPE=Debug` ..

Before that, I deleted the folder bin in the root directory of jpscore.

After I updated boost (1.66->1.70), the error still occurs.

@gjaeger Ah I am only linking filesystem for apple clang, I can fix that =) . I will open up a PR asap. Would be nice if you could verify this
