编译Qt
qt-everywhere-src-5.11.3.tar.xz
qt-creator-opensource-src-4.8.2.tar.gz
linuxdeployqt-master.tar.gz
;; Qt直接configure编译 -slient可以减少输出
yum install libxcb libxcb-devel xcb-util xcb-util-devel mesa-libGL-devel libxkbcommon-devel
export QT_DIR=/usr/local/Qt-5.11.3
export PATH=$QT_DIR/bin:$PATH
export LD_LIBRARY_PATH=$QT_DIR/lib:$LD_LIBRARY_PATH
;; qt-creator
qmake -r
make
不需要 install, 直接拷贝到 /opt 执行 bin/qtcreator
install 需要指定INSTALL_ROOT目录，不然会安装到根目录
;; 修改 linuxdeployqt源码，不使用appimage和patchelf
yum install patchelf
mkdir build
qmake ..
make
cp bin/linuxdeployqt /usr/bin
