[CMake] [CMAKE] make package works but ninja package does not

[Alfred Sawaya]

The only difference is about the usage of preinstall target. The Ninja
generator does not use it, and it should because it need to build sqlcipher
before packaging it...

the interesting part of vimdiff of cpack --trace :

*        Unix Makefiles                                   |
 Ninja*
  CPack: Install projects                              |  CPack: Install
projects
  ---------------------------------------------- --------|  CPack: - Run
preinstall target for: sqlcipher
  CPack: - Install project: sqlcipher             |  CPack: - Install
project: sqlcipher
