Unable to build TensorRT library about hyperpose

[PrinceP]

Install gflags.
sudo apt-get install libgflags-dev

[sjdrc]

Sorry, should have mentioned that I had already installed that package. No luck and still get the warning though. I'm running Ubuntu 16.04.

Clone the repo https://github.com/gflags/gflags
And try to install it using make.
What is output of dpkg --listfiles libgflags-dev

[sjdrc]

Ubuntu 16.04 version of gflags didn't include cmake files. Fixed that issue by building from source. Still getting this error:

CMake Error at cmake/3rdparty.cmake:20 (ADD_LIBRARY):
   No SOURCES given to target: tracer
 Call Stack (most recent call first):
   CMakeLists.txt:17 (INCLUDE)



 CMake Error at cmake/3rdparty.cmake:38 (ADD_LIBRARY):
   No SOURCES given to target: stdtensor
 Call Stack (most recent call first):
   CMakeLists.txt:17 (INCLUDE)

[sjdrc]

So after trying Ubuntu's version of CMake (3.5.1) it works, but gives this message

You have called ADD_LIBRARY for library tracer without any source files. This typically indicates a problem with your CMakeLists.txt file
You have called ADD_LIBRARY for library stdtensor without any source files. This typically indicates a problem with your CMakeLists.txt file

I've been using a self compiled version of 3.12. It looks like the newer version is enforcing an error where the previous version printed it but still allowed you to continue.
