 ####CMake Variables
 
 #####BUILD_ONLY
-Allows you to only build the clients you want to use. This will resolve low level client dependencies if you set this to a high-level sdk such as aws-sdk-cpp-transfer. This will also build integration and unit tests related to the projects you select if they exist. aws-sdk-cpp-core always builds regardless of the value of this argument. This is a list argument. Example: -DBUILD_ONLY="aws-sdk-cpp-s3;aws-sdk-cpp-dynamodb;aws-sdk-cpp-cognito-identity"

 #####ADD_CUSTOM_CLIENTS
 Allows you to build any arbitrary clients based on the api definition. Simply place your definition in the code-generation/api-definitions folder. Then pass this arg to cmake. The cmake configure step will generate your client and include it as a subdirectory in your build. This is particularly useful if you want to generate a C++ client for using one of your API Gateway services. To use this feature you need to have python 2.7, java, jdk1.8, and maven installed and in your executable path. Example: -DADD_CUSTOM_CLIENTS="serviceName=myCustomService; version=2015-12-21;serviceName=someOtherService; version=2015-08-15"
