Fix catkin workspace, can't launch newly compiled nodes

edit

Hello I'm having issues running new modules, the compilation goes right but rosrun can't find the new nodes, i guess it's en environment issue, but as I'm a noob, it's just a guess :)

I have the catkin ws under ~/ros_ws/, in this folder i have my package pcltest, that have a single source file src/pcltest_node.cpp When i run catkin_make i can see the compilation having success:

...
[100%] Building CXX object pcltest/CMakeFiles/pcltest_node.dir/src/pcltest_node.cpp.o
Linking CXX executable pcltest_node
[100%] Built target pcltest_node
...

And I can find my binary compiled in ~/ros_ws/build/pcltest/pcltest_node

This is the output of catkin_make install

-- Install configuration: ""
-- Up-to-date: /home/cesare/ros_ws/install/_setup_util.py
-- Up-to-date: /home/cesare/ros_ws/install/env.sh
-- Up-to-date: /home/cesare/ros_ws/install/setup.bash
-- Up-to-date: /home/cesare/ros_ws/install/setup.sh

-- Up-to-date: /home/cesare/ros_ws/install/share/pcltest/cmake/pcltestConfig-version.cmake
-- Up-to-date: /home/cesare/ros_ws/install/share/pcltest/package.xml

then usually I source /home/cesare/ros_ws/install/setup.bash but when i try to run the node with rosrun pcltest xxx i have an error, it looks like it's not copying the binary from the build to the install folder... what am I doing wrong ?

----- ----- ----- EDIT ----- ----- -----
I've tried to source /home/cesare/ros_ws/devel/setup.bash but it doesn't change much. In both the cases rosrun is able to find (and autocoplete) the package but it can't find che binary :(

This is how it looks my 'devel/share' dir

.
└── pcltest
    └── cmake
        ├── pcltestConfig.cmake
        └── pcltestConfig-version.cmake

This is the install/share dir

.
└── pcltest
    ├── cmake
    │   ├── pcltestConfig.cmake
    │   └── pcltestConfig-version.cmake
    └── package.xml

This is the package in the build dir
