QT Error: cannot find -lGL

[cxam]

Hi! I Just installed Qt5 on my Debian machine with LXDE in order to Cross-Compile to raspberry pi but I just made a new project (I only generated the files and I compiled it) and stopped with the error

:-1: error: cannot find -lGL
:-1: error: collect2: error: ld returned 1 exit status

Thanks In advance :)
