[Discuss-gnuradio] [UHD] CMake Error: The following variables are used in this project, but they are set to NOTFOUND.

I have compiled and run UHD code that was downloaded one day in last week.

One problem was that "tx_timed_samples.cpp" does not work. 

The timing control didn't work.

Even I give 10 secs delay, the code just promptly send samples without any delay.

Whereas receiver properly wait for the specified time before starting the reception process.

Therefore, I have updated UHD code today by

- "git pull" in /root/git/uhd/

- "cmake ../" in /root/git/uhd/build

got following error
