编译OpenSSL

在 Linux 下自定义OpenSSL库，需要安装到一个路径，以便curl能找到。

./config --prefix=/home/u0u0/works/projects/Cocos2d-thirdpart/tarballs/openssl_install --openssldir=/home/u0u0/works/projects/Cocos2d-thirdpart/tarballs/openssl_install
make
make install

编译curl

./configure --enable-static --disable-ldap --enable-ipv6 --with-zlib=/home/u0u0/works/Cocos2d-thirdpart/tarballs/zlib-1.2.8/ --with-ssl=/home/u0u0/works/projects/Cocos2d-thirdpart/tarballs/openssl_install --prefix=/home/u0u0/works/projects/Cocos2d-thirdpart/tarballs/curl_install
make
make install

编译OpenAL

$sudo apt-get install libasound2-dev
$cmake .. -DLIBTYPE=STATIC -DALSOFT_INSTALL=OFF -DALSOFT_REQUIRE_ALSA=ON
