Sometimes you want to add your own symbol definitions to a project so that the IDE automatically includes them at the beginning of each source-code file when building the project.

The following example shows a custom symbol definition in the C or C++ programming language:

#define GLOBAL_DEBUG

Perhaps you wish to define the GLOBAL_DEBUG symbol only when building development versions of your code, but exclude the definition before shipping your final product.

To achieve this goal, create a precompiled header and insert the symbol definition into the header. See "Using Precompiled or Preprocessed Headers" for more information.
