Summary

0031606: Configuration, CMake - build fails with Android NDK + CLang compiler + MinGW Makefiles

Description

Building with Android NDK 21c on Windows leads to the following error:

clang++: warning: argument unused during compilation: '-s' [-Wunused-command-line-argument]
c:\android-ndk-r21c\toolchains\llvm\prebuilt\windows-x86_64\bin/../lib/gcc/aarch64-linux-android/4.9.x/../../../../aarch64-linux-android/bin\ld: 
unrecognized option '--export-all-symbols'
c:\android-ndk-r21c\toolchains\llvm\prebuilt\windows-x86_64\bin/../lib/gcc/aarch64-linux-android/4.9.x/../../../../aarch64-linux-android/bin\ld: 
use the --help option for usage information
clang++: error: linker command failed with exit code 1 (use -v to see invocation)

Apparently, this happens due to "if(MINGW)" checks in CMake scripts intended only for GCC compiler and Windows target platform introduces by 0027197.

Steps To Reproduce

  cmake -G "MinGW Makefiles" ^
 -D CMAKE_SYSTEM_NAME:STRING="Android" ^
 -D CMAKE_ANDROID_NDK="c:/android-ndk-r21c" ^
 -D CMAKE_BUILD_TYPE:STRING="Release" ^
 -D CMAKE_ANDROID_ARCH_ABI:STRING="arm64-v8a" ^
 -D CMAKE_SYSTEM_VERSION:STRING="21" ^
 -D CMAKE_ANDROID_STL_TYPE="c++_shared" ^
 -D BUILD_LIBRARY_TYPE:STRING="Shared" ...
