echo 第1步：检查编译模式debug/release...
echo ---------------------------------------------------------------

echo 第2步：清理编译临时文件...
echo ---------------------------------------------------------------

rm -rf $build_cache_path

echo 第3步：生成ninja编译文件..
echo ---------------------------------------------------------------

echo ---------------------------------------------------------------
echo 第4步：开始ninja编译...
echo ---------------------------------------------------------------
# build
$ninja -C $build_cache_path > $log_path
if [ $? != 0 ]; then
    echo "build failed. log: $log_path"
    exit 1
