 ./configure -release -opensource -nomake examples -nomake tests -recheck-all
sudo ./configure -platform linux-aarch64-gnu-g++ -nomake examples -nomake tests -opensource -skip qt3d

执行./configure 出现："You don't seem to have 'make' or 'gmake' in your PATH" 

sudo apt-get install build-essential 

如果还不能解决，手动指定$MAKE 

export MAKE=/usr/bin/make

export QTDIR=/usr/local/Qt-5.9.9
export PATH=$QTDIR/bin:$PATH
export MANPATH=$QTDIR/man:$MANPATH
export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
