cmake常用編譯選項

1、openmp加載，cmake3.9之后內置了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不同會引發編譯錯誤

可通過ANDROID_STL設置

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

3、可設置輸出路徑,ARCHIVE_OUTPUT_DIRECTORY表征靜態庫路徑，LIBRARY_OUTPUT_DIRECTORY為動態庫路徑

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

4、
