Install basic build package install

install build-essential
```
  sudo apt-get install build-essential
```
install ‘cmake’
```
  sudo apt-get install cmake
```
install ‘make’
```
  sudo apt-get install make
```

Install library package

libdmg-hfsplus explain how to build but this explaination included assumption that zlib source is in dmg directory
to build dmg lib first of all install ‘zlib development package’
```
  sudo apt-get install -y zlib1g-dev
```
Second install open ssl
```
  sudo apt-get install -y openssl
```

build

to build DMG libaray in libdmg source, bellow command is official
```
  cd dmg/zlib-1.2.3
  ./configure
  make
  cd ..
  make
```
but this way is not good way, becasue we have to download zlib source and build it

so I just using zlib package(zlib1g-dev)

  $ cd dmg
  $ cmake ./CMakeLists.txt 
  $ make

it make error, because header files path so it is not right way.
actually all of header files is in includes folder, so if you want include headers, you should build on root folder
just run cmake command in source root folder
```
  $cmake ./CmakeLists.txt
```
cmake makes build configs and make files
and make package
```
  $make dmg
  $cd dmg
  $make
```
into dmg folder and command ‘make’,
first ‘make dmg’ make dmg.a library, second go into dmg foler and ‘make’ create dmg binary.
if build is success, you can see dmg binary in ./dmg folder
unfortunatly sombody can see error like
- ‘error: field ‘hmacCTX’ has incomplete type’ error
- this error
- the reason happen this error is open ssl API.
- HMAC_CTX is changed openssl after 1.1.0 version
- so if you want build with open ssl version after 1.1.0, you should change some code.
- but we have simple solution. https://github.com/planetbeing/libdmg-hfsplus/blob/openssl-1.1 branch
- if you meet this error, please use openssl-1.1 branch code
