add_definitions¶
Add -D define flags to the compilation of source files.
add_definitions(-DFOO -DBAR ...)
Adds definitions to the compiler command line for targets in the current directory, whether added before or after this command is invoked, and for the ones in sub-directories added after. This command can be used to add any flags, but it is intended to add preprocessor definitions.
Note
This command has been superseded by alternatives:
- Use - add_compile_definitions()to add preprocessor definitions.
- Use - include_directories()to add include directories.
- Use - add_compile_options()to add other options.
Flags beginning in -D or /D that look like preprocessor definitions are
automatically added to the COMPILE_DEFINITIONS directory
property for the current directory.  Definitions with non-trivial values
may be left in the set of flags instead of being converted for reasons of
backwards compatibility.  See documentation of the
directory,
target,
source file COMPILE_DEFINITIONS
properties for details on adding preprocessor definitions to specific
scopes and configurations.
