Cmake交叉编译编译动态库

cmakelists.txt写法如下

 

编译指令：cmake -DCMAKE_CXX_COMPILER:FILEPATH=/home/wangwc/CompilerCollection/RuiXinWei/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++ …

 

aux_source_directory:遍历./ITA_LIB目录的文件存放到ITA_LIB_DIR中。

 

add_library:编译动态库

 

add_compile_options:忽略编译警号
