Qt5.7.1添加支持openssl

./config no-asm shared --prefix=/opt/Xilinx2018_zynq/zynq_openssl_1.0.2/ --cross-compile-prefix=/opt/Xilinx/SDK/2018.3/gnu/aarch32/lin/gcc-arm-linux-gnueabi/bin/arm-linux-gnueabihf-

make -j4

make install

1.
首先确保qt源码目录下交叉编译命令生效
cd qt-everywhere-opensource-src-5.7.1 
source /opt/Xilinx/SDK/2018.3/settings64.sh

2.执行configure，其配置如下：
./configure -xplatform arm-linux-gnueabihf-g++ \
    -openssl-linked \
    -I/opt/Xilinx2018_zynq/zynq_openssl_1.0.2/include \
    -L/opt/Xilinx2018_zynq/zynq_openssl_1.0.2/lib -lssl -lcrypto \
