Prevents some unicode-related compiler definitions being set automatically on a target.

The command is defined in the Core component of the Qt6 package. Load the package with:

find_package(Qt6 REQUIRED COMPONENTS Core)

This command was introduced in Qt 6.2.



If versionless commands are disabled, use qt6_disable_unicode_defines() instead. It supports the same set of arguments as this command.


In Qt 6, the UNICODE and _UNICODE compiler definitions are set by default for targets that link against Qt modules. This is in line with the qmake behavior, but it is a change compared to the CMake API behavior in Qt 5. Calling qt_disable_unicode_defines() on a target prevents these compiler definitions from being automatically set.
