build error on Linux about fuji-cam-wifi-tool

[etkayapar]

Scanning dependencies of target fuji_cam_wifi_tool
[ 92%] Building CXX object tool/CMakeFiles/fuji_cam_wifi_tool.dir/src/main.cpp.o
/mnt/sviluppo/fuji-tool/fuji-cam-wifi-tool/tool/src/main.cpp:38:6: error: ‘timed_mutex’ in namespace ‘std’ does not name a type
std::timed_mutex g_comm_lock;

I was also getting this error under Ubuntu 18.04 using @mzealey s fork. but that was the only error for me. I solved that by adding

#include <mutex>

to the begginning of /tool/src/main.cpp (around the other includes like #include <algorithm>

Hope that helps you too!

It compiles with your suggested fix, thanks

Should be fixed in c597fc4, but I have not tested it on Linux.
