Compiling C++ Paho MQTT code gives error "Could not find Paho MQTT C library"

I'm using Ubuntu 16.04, I cloned the c library at ~/Paho_MQTT/paho_c and ran following commands in paho.mqtt.c folder,
sudo apt-get install build-essential gcc make cmake cmake-gui cmake-curses-gui
sudo apt-get install fakeroot fakeroot devscripts dh-make lsb-release
sudo apt-get install libssl-dev
sudo apt-get install doxygen graphviz
mkdir build
cd build
ccmake ..
make
sudo make install
All goes well.
Then I cloned c++ code at ~/Paho_MQTT/paho_cpp, and ran following commands in the paho.mqtt.cpp folder,
mkdir build
cd build
cmake -DPAHO_MQTT_C_PATH=~/Paho_MQTT/paho_c/paho.mqtt.c ..
Here I get error, "Could not find Paho MQTT C library",
Can you please suggest any solution ?

Need help to install c++ grpc on ubuntu 16.04

I tried to install grpc by executing the following
git clone -b $(curl -L http://grpc.io/release) https://github.com/grpc/grpc
cd grpc
git submodule update --init
make
But when I run make, I get the message "#error This file was generated by an older version of protoc which is"
But, I have the latest protoc installed ...
/usr/bin/protoc --version
libprotoc 3.2.0

Posting an answer to my own question ...
The issue gets resolved when I remove the third party protobuf files before running install.
rm -rf third_party/protobuf
I am not exactly sure why this works though ...

Compiling libsass in Docker container

So I have the following Dockerfile:
############################################################
# Based on Ubuntu
############################################################
FROM ubuntu:trusty
MAINTAINER OTIS WRIGHT
# Add extra software sources
RUN apt-get update -qq
# Libsass requirements.
RUN apt-get install -y curl git build-essential automake libtool
# Fetch sources
RUN git clone https://github.com/sass/libsass.git
RUN git clone https://github.com/sass/sassc.git libsass/sassc
# Create configure script
RUN cd libsass
RUN autoreconf --force --install
RUN cd ..
# Create custom makefiles for **shared library**, for more info read:

RUN cd libsass

RUN ./configure --disable-tests --enable-shared --prefix=/usr
RUN cd ..
# Build the library
RUN make -C libsass -j5
# Install the library
RUN make -C libsass -j5 install
I am trying to build libsass based on this gist:
https://gist.github.com/edouard-lopez/503d40a5c1a49cf8ae87
However when I try to build with docker I get the following error:
Step 11 : RUN git clone https://github.com/sass/libsass.git
---> Using cache

Step 12 : RUN git clone https://github.com/sass/sassc.git libsass/sassc

Step 13 : RUN cd libsass

Step 14 : RUN autoreconf --force --install
---> Running in a9b0d51d6ee3
autoreconf: 'configure.ac' or 'configure.in' is required
The command '/bin/sh -c autoreconf --force --install' returned a non-zero code: 1
I don't know a lot about compiling from source so any solutions please walk me through.

Docker won't change dirs for you RUN cd libsass so you need to path your commands or use the WORKDIR directive

The OpenNi2 (and Nite) project was discontiued when apple bought primesense. Using google you may find a million instructions of how or where to find them.
Then again, some other companies have done some updates that may help you. One of this companies is occipital structure:
https://github.com/occipital/openni2
In the github readme you will find the instructions of how to install it in different systems.
Nite2 is a little more difficult to find since the license is different and I think I can't post it here. For the installing instructions, it is similar to the ones of openni2 and are also in the readme file of the package.
