#351 When CCI is installed on Mac OS X, the libraries have extension .dylib not .so as on Linux

[Jira Trac]

I've just installed CUBRID CCI driver on Mac OS X following [this tutorial|https://github.com/kadishmal/cubrid-mac-os-x].

On Mac OS X platform *make* program always creates libraries with .dylib* extension. Linux compilers create *.so* libraries. After installing CCI driver, we have the following files on Mac OS X.

- libcascci.8.dylib
- libcascci.a
- libcascci.dylib - libcascci.8.dylib
- libcascci.la

Since CUBRID PHP and PDO drivers (and probably other drivers as well) try to link to *libcascci.so*, users on Mac need to manually create a symlink for libcascci.8.dylib. Which is not very convenient.

It would be very nice and convenient if CUBRID driver installers (Makefiles) tested if this is Mac OS X or not (ifdef DARWIN), then link to *libcascci.dylib* instead of *libcascci.so*.

Please add this to CUBRID drivers. You may refer to how MySQL does this.
