live555交叉编译提示openssl找不到

首先交叉编译openssl。
将openssl/lib下面的文件拷贝到交叉编译器如下目录

/home/ctools/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/arm-linux-gnueabihf/libc/usr/lib/arm-linux-gnueabihf

将openssl/include下面的openssl文件夹拷贝到交叉编译器如下目录

/home/ctools/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/arm-linux-gnueabihf/libc/usr/include$

config.armlinux文件如下：
