由于最近急需的一个项目，需要hdf5库，误打误撞，编译成功。特此记录
官网下载地址：https://portal.hdfgroup.org/display/support/HDF5+1.12.2#files
找到如下地址，本人电脑有cmake软件，我下载了Cmake版本和源代码版本同时进行了，事实上我也下载了源码进行cmake手工编译，但是不如直接下载CMake版本的来的方便，所以这里我直接记录了Cmake版本的编译方法
如果下载不了，可以通过该链接进行下载
如果不想看怎么编译，可以从这里下载我编译好的库
1、下载解压（注意路径，最好不要有中文路径，个人习惯）
2、进入文件夹后，如下图
3、该文件夹下有很多批处理文件，由于我电脑上有VS2017,所以我默认使用“build-VS2017-64_debug.bat”文件。
4、点击“build-VS2017-64.bat”以管理员方式运行，剩下就是看着cmd窗口不断的编译、等待…
5、无尽等待完后，就是查看成果了。该编译的成果就在“build-VS2017-64.bat”同级文件夹的“HDF5-1.12.2-win64.zip”压缩包（我是后面改名：HDF5-1.12.2-win64_release.zip，由于这个bat处理里面是只编译Release版本，Debug版本需要再单独编译，我是在后面配置测试才发现这个问题，这里我就不记录怎么走的弯路了）
6、Debug版本编译：更改“HDF5-1.12.2-win64.zip”为“HDF5-1.12.2-win64_release.zip”，避免编译debug版本的时候被覆盖了。复制一份“build-VS2017-64.bat”改名为“build-VS2017-64_debug.bat”，用notepad打开后，将“Release”更换为“Debug”即可
7、点击“build-VS2017-64_debug.bat”以管理员方式运行，剩下就是看着cmd窗口不断的编译、等待…
8、更改“HDF5-1.12.2-win64.zip”为“HDF5-1.12.2-win64_debug.zip”,将debug压缩包和release压缩包解压，然后进行“bin”文件夹、“lib”文件夹合并即可。
Debug lib文件加载下面即可：
libaec_D.lib
libhdf5_D.lib
libhdf5_cpp_D.lib
libhdf5_hl_D.lib
libhdf5_hl_cpp_D.lib
libhdf5_tools_D.lib
libszaec_D.lib
libz_D.lib
