cmake常用编译选项

Posted 2020-12-29 zl1991

1、openmp加载，cmake3.9之后内置了openmp

find_package(OpenMP)
if (OPENMP_FOUND OR OpenMP_CXX_FOUND) 
　　 set (CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}")
    set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")
    set (CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} ${OpenMP_EXE_LINKER_FLAGS}")
endif()

2、引用的c++11不同会引发编译错误

可通过android_STL设置

-DANDROID_STL="gnustl_static"
或
-DANDROID_STL="c++_static"

3、可设置输出路径,ARCHIVE_OUTPUT_DIRECTORY表征静态库路径，LIBRARY_OUTPUT_DIRECTORY为动态库路径

set_target_properties( smaple PROPERTIES ARCHIVE_OUTPUT_DIRECTORY  "./out/${ANDROID_ABI}" )

4、
