一：声明

请用自带的交叉编译器编译，openssl curl也要交叉编译

1:编译ake文件

cmake_minimum_required( VERSION 2.6.3 )
if( DEFINED CMAKE_CROSSCOMPILING )

# subsequent toolchain loading is not really needed
message("DEFINED CMAKE_CROSSCOMPILING")
return()

endif()

if( CMAKE_TOOLCHAIN_FILE )

# touch toolchain variable to suppress "unused variable" warning

endif()

if( CMAKE_VERSION VERSION_GREATER "3.0.99" )

set( CMAKE_SYSTEM_NAME Generic )
message("set CMAKE_SYSTEM_NAME Generic")
else()

set( CMAKE_SYSTEM_NAME Linux )
message("set CMAKE_SYSTEM_NAME Linux")

endif()

set( TOOLCHAIN_PATH "/opt/arm/opt/ext-toolchain" )
set( CMAKE_C_COMPILER "/opt/arm/opt/ext-toolchain/bin/arm-linux-gnueabihf-gcc" )
set( CMAKE_CXX_COMPILER "/opt/arm/opt/ext-toolchain/bin/arm-linux-gnueabihf-g++" )

CMAKE命令：

cmake -DCMAKE_TOOLCHAIN_FILE=./ake
            -DCMAKE_INSTALL_PREFIX=/usr/local/arm_aliyun-oss
           -DBUILD_SHARED_LIBS=OFF
           -DENABLE_RTTI=OFF
           -DOPENSSL_ROOT_DIR=/usr/local/arm_openssl1.1.0l
          -DOPENSSL_INCLUDE_DIRS=/usr/local/arm_openssl1.1.0l/include
          -DOPENSSL_LIBRARIES=/usr/local/arm_openssl1.1.0l/lib
          -DCURL_INCLUDE_DIR=/usr/local/arm_curl7.60/include
          -DCURL_LIBRARY=/usr/local/arm_curl7.60/lib
