WSL安装bcolz

pip install bcolz老是出错，去Blosc/bcolz上找到Compiling with an installed Blosc library (recommended)的办法。

1. 首先从Blosc/c-blosc/releases下载源码
2. tar.gz解压命令tar -zxvf
3. 一切按README.md的操作，例如，输入cmake -DCMAKE_INSTALL_PREFIX=/usr/local
4. 遇到No CMAKE_CXX_COMPILER could be found.的错误，需要执行sudo apt-get install g++
5. 若遇到
