[Nektar-users] How can I run ADRSolver to solve the first example?

Dear Nektar community, I am a newbie in Nektar. I am very interested in Spectral Element method. I have installed Nektar in my Ubuntu computer and completed test with ctest. Now I tried to run the first example in 6.4.1 1D Advection equation in the manual. I went to the folder and run ADRSolver Advection1D.xml. But, I got the following error message; ADRSolver: command not found. Please let me know how to do run it. Is there any other environmental setting? Best regards, Donmyung Suh
