不能交叉编译cURL与Windows的OpenSSL支持

Question

我试图从Linux（Debian Jessie）为Windows交叉编译。我编译了zlib和OpenSSL，并且cURL的配置脚本确实找到了这些库，但仍然表示SSL支持已关闭。

这是构建脚本我用：

# ZLIB 
cd /builds 
curl -O -J http://www.zlib.net/zlib-1.2.11.tar.gz 
tar xf zlib-1.2.11.tar.gz 
cd /builds/zlib-1.2.11 
CC=x86_64-w64-mingw32-gcc ./configure --prefix=/usr/x86_64-w64-mingw32 --static 
make && make install 

# OPENSSL 
cd /builds 
curl -O -J https://www.openssl.org/source/openssl-1.1.0c.tar.gz 
tar xf openssl-1.1.0c.tar.gz 
cd /builds/openssl-1.1.0c 
CROSS_COMPILE="x86_64-w64-mingw32-" ./Configure -DHAVE_STRUCT_TIMESPEC -lz -lws2_32 zlib mingw64 no-shared --prefix=/usr/x86_64-w64-mingw32 
make depend 
make && make install 

# CURL 
cd /builds 
curl -O -J https://curl.haxx.se/download/curl-7.52.1.tar.gz 
cd /builds/curl-7.52.1 
./configure --prefix=/usr/x86_64-w64-mingw32 --host=x86_64-w64-mingw32 --enable-optimize --with-ssl=/usr/x86_64-w64-mingw32 

它发现库成功，但随后SSL刚禁用，因为缺少--with-ssl

要用ssl支持交叉编译curl，我直接在CPP_FLAGS和LD_FLAGS提供位置，而不是pro viding路径与--with-ssl：

export DESTDIR="$CURL_INSTALL_DIR" 
export CPPFLAGS="-I${OPENSSL_INSTALL_DIR}/include -I${ZLIB_INSTALL_DIR}/include" 
export LDFLAGS="-L${OPENSSL_INSTALL_DIR}/lib -L${ZLIB_INSTALL_DIR}/lib" 
export LIBS="-lssl -lcrypto" 

CURL_ARGS="--with-ssl --with-zlib --disable-ftp --disable-gopher 
    --disable-file --disable-imap --disable-ldap --disable-ldaps 
    --disable-pop3 --disable-proxy --disable-rtsp --disable-smtp 
    --disable-telnet --disable-tftp --without-gnutls --without-libidn 
    --without-librtmp --disable-dict" 

chmod 777 buildconf 
./buildconf 
./configure --host="${CROSS_COMPILE}" $CURL_ARGS 

make -j16 
make install
