Tweaked cmake files to make build work on OSX

Borrowed a lot from the cpprestsdk CMAKE, the changes revolved around:
* using the correct OpenSSL, because homebrew installs it "Keg Only"
* injecting a missing -L directive for gettext (libintl)
* adding -DBOOST_LOG_DYN_LINK to make boost link properly
* adding the same warnings/suppressions/cflags as Casablanca

 Please note the current build script is only tested on Ubuntu 14.04. Please update the script accordingly for other distributions.
 
+## Getting Started on OSX
+
+*Note that OSX is not officially supported yet, but it has been seen to work, YMMV. This build has been tested to work when the dependencies are installed via homebrew, YMMV if using FINK or MacPorts*
+
+Install dependecies with homebrew:
+
+```
+brew install glibmm libxml++ libsigc++ ossp-uuid gettext openssl
+```
+
+As mentioned above, the Azure Storage Client Library for C++ depends on Casablanca. Follow [these instructions](https://github.com/Microsoft/cpprestsdk/wiki/How-to-build-for-Mac-OS-X) to compile it. Current version of the library depends on Casablanca version 2.8.0.
+
+Once this is complete, then:
+
+- Clone the project using git:
+```bash
+git clone https://github.com/Azure/azure-storage-cpp.git
+```
+The project is cloned to a folder called `azure-storage-cpp`. Always use the master branch, which contains the latest release.
+- Install additional dependencies:
+```bash
+sudo apt-get install libxml++2.6-dev libxml++2.6-doc uuid-dev
+```
+- Build the SDK for Release:
+```bash
+cd azure-storage-cpp/Microsoft.WIndowsAzure.Storage
+mkdir build.release
+cd build.release
+CASABLANCA_DIR=<path to Casablanca> cmake .. -DCMAKE_BUILD_TYPE=Release -DOPENSSL_ROOT_DIR=<path to openssl> -DGETTEXT_LIB_DIR=<path to gettext lib dir>
+make
+```
+In the above command, replace `<path to Casablanca>` to point to your local installation of Casablanca. <path to openssl> to your local openssl, it is recommended not to use the version that comes with OSX, rather use one from Homebrew or the like. <path to gettext lib dir> is similar, although you go all the way to the lib dir. For example, if the file `libcpprest.so` exists at location `~/Github/Casablanca/cpprestsdk/Release/build.release/Binaries/libcpprest.so`, and you've installed the dependencies through homebrew then your `cmake` command should be:
+```bash
+CASABLANCA_DIR=~/Github/Casablanca/cpprestsdk cmake .. -DCMAKE_BUILD_TYPE=Release -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl -DGETTEXT_LIB_DIR=/usr/local/opt/gettext/lib
+```
+The library is generated under `azure-storage-cpp/Microsoft.WindowsAzure.Storage/build.release/Binaries/`.
+
+*As yet the unit tests don't build, because cmake won't find UnitTest++ even though it is installed via Homebrew*
