configure CodeBlock for PCL

[mifum]

Hi all,
I installed PCL on my computer with Ubuntu 12.04 LTS folowing instructions find here: http://pointclouds.org/downloads/linux.html

Then I followed the first tutorial found here: http://pointclouds.org/documentation/tutorials/writing_pcd.php#writing-pcd

Then I typed this commands on terminal to generate CodeBlocks project: cmake -G"CodeBlocks - Unix Makefiles" /home/.../dev/PCL/CMakeLists.txt


I got the CodeBlock project. I compiled it without errors, but when I try to run it says: You can't "run" a commands-only target...

What is the problem?

Thank you a lot in advance!!
