Get trouble in compiling glog for android!

[CarlLyt]

Hello everybody.
before compiling, i successfully installed gflag, so there was no warning when i Configure and Generate the glog.
(compile env: win10 ndk17 CMake3.12 MinGW)

then i was met errors like this:
D:\Restor\chajian\glog-0.3.5\build>make
[ 44%] Built target glog
[ 55%] Built target utilities_unittest
[ 66%] Built target demangle_unittest

If you look into $ANDROID_NDK/toolchains/llvm/prebuilt/linux-x86_64/sysroot/usr/include/glob.h, you'll find that at least Android API Level 28 (Android 9, "Pie") is required for glob().

However, this is just the compilation of a unittest that fails due to it's reliance on glob(). The library itself doesn't need it. And you don't need those unittests, especially when cross-compiling. So it's enough to just disable BUILD_TESTING in your cmake config.
