qt cross compile on raspberry pi3

[Momeneh]

Hi, i used bellow link for cross compile:
https://wiki.qt.io/RaspberryPi2EGLFS
every thing is ok, but when i use of "make" command after bellow command:
./configure -release -opengl es2 -device linux-rasp-pi3-g++ -device-option CROSS_COMPILE=~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf- -sysroot ~/raspi/sysroot -opensource -confirm-license -make libs -prefix /usr/local/qt5pi -extprefix ~/raspi/qt5pi -hostprefix ~/raspi/qt5 -v -no-use-gold-linker
i deal with bellow error :
make[1]: Nothing to be done for 'first'.
my ubuntu version is 18.04 LTS and my qt version is 5.9.
if you can, please help me for solving this problem.
thank you.

@Momeneh This is not an error.
Is it possible that you already built it before in same location?
Did configure really finish without any errors?

In the uploaded picture you can see output of bellow command:
./configure -release -opengl es2 -device linux-rasp-pi3-g++ -device-option CROSS_COMPILE=~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf- -sysroot ~/raspi/sysroot -opensource -confirm-license -make libs -prefix /usr/local/qt5pi -extprefix ~/raspi/qt5pi -hostprefix ~/raspi/qt5 -v -no-use-gold-linker

@Momeneh Did you already build before in same directory?

[Momeneh]

no, but i'm not sure:(

of course you should know, before that I had several problems with the configure command so i couldn't continue, eventually i solved them and removed all the files or folders related to them and tried again and created raspi file at home and continued
i used bellow link:
https://wiki.qt.io/RaspberryPi2EGLFS

so i think that it have not build before in the same directory
