CMAKE交叉编译android库

不管是在Windows，还是Ubuntu平台，

cmake -G"Unix Makefiles" -DCMAKE_TOOLCHAIN_FILE=F:/Download/android-ndk-r21-windows-x86_64/android-ndk-r21/build/cmake/android.toolchain.cmake -DANDROID_NDK=F:/Download/android-ndk-r21-windows-x86_64/android-ndk-r21 -DCMAKE_SYSTEM_NAME=Android -DANDROID_PLATFORM=android-27 -DCMAKE_BUILD_TYPE=Release -DANDROID_ABI=arm64-v8a -DAndroid=ON -DANDROID_STL=c++_static -DCMAKE_CXX_STANDARD=11 -DANDROID_NATIVE_API_LEVEL=21 ..

一定记得是外部指定CMAKE_TOOLCHAIN_FILE，在CMakeLists.txt内部指定是会出错的(而且是在make阶段报错，cmake阶段不报)，且错误千奇百怪，切记切记~
