[Bug]: cmake指定Release编译报错

[dreamcmi]

What happened?

使用master分支编译xquic会出现错误
commit id 6348479fbd8611034dfd5e633b59ef31931da94b
系统Ubuntu 20.04 focal x86_64 Linux 5.15.0-56-generic
以下是编译命令

# 获取 XQUIC 源码
git clone https://github.com/alibaba/xquic.git
cd xquic

# 编译 BabaSSL
git clone -b 8.3-stable https://github.com/Tongsuo-Project/Tongsuo.git ./third_party/babassl
cd ./third_party/babassl/
./config --prefix=/usr/local/babassl
make -j
SSL_TYPE_STR="babassl"
SSL_PATH_STR="${PWD}"
SSL_INC_PATH_STR="${PWD}/include"
SSL_LIB_PATH_STR="${PWD}/libssl.a;${PWD}/libcrypto.a"
cd -

git submodule update --init --recursive
mkdir -p build; cd build
cmake -DSSL_TYPE=${SSL_TYPE_STR} -DSSL_PATH=${SSL_PATH_STR} -DSSL_INC_PATH=${SSL_INC_PATH_STR} -DSSL_LIB_PATH=${SSL_LIB_PATH_STR} ..
make

cmake日志输出如下

Steps To Reproduce

cmake -DSSL_TYPE=${SSL_TYPE_STR} -DSSL_PATH=${SSL_PATH_STR} -DSSL_INC_PATH=${SSL_INC_PATH_STR} -DSSL_LIB_PATH=${SSL_LIB_PATH_STR} ..
make
