# qt_add_big_resources

Compiles big binary resources into object code.

The command is defined in the `Core` component of the `Qt6` package, which can be loaded like so:

     find_package(Qt6 REQUIRED COMPONENTS Core)

This command was introduced in Qt 5.12.

## Synopsis

     qt_add_big_resources(<VAR> file1.qrc [file2.qrc ...]
                          [OPTIONS ...])

If versionless commands are disabled, use `qt6_add_big_resources()` instead. It supports the same set of arguments as this command.

## Description

Creates compiled object files from Qt resource files using the Resource Compiler (rcc). Paths to the generated files are added to `<VAR>`.

This is similar to qt_add_resources, but directly generates object files (`.o`, `.obj`) files instead of C++ source code. This allows to embed bigger resources, where compiling to C++ sources and then to binaries would be too time consuming or memory intensive.

Note: The `file1.qrc` will not be treated as a source file by Qt Creator. It needs to be added as a source file to a CMake target and have the property `SKIP_AUTORCC` set to `ON`.

Warning: This command is not supported when building for iOS, use qt_add_resources instead. See QTBUG-103497 for details.

## Arguments

You can set additional `OPTIONS` that should be added to the `rcc` calls. You can find possible options in the rcc documentation.

## Examples

     set(SOURCES main.cpp)
     qt_add_big_resources(SOURCES big_resource.qrc)

     # Have big_resource.qrc treated as a source file by Qt Creator
     list(APPEND SOURCES big_resource.qrc)
     set_property(SOURCE big_resource.qrc PROPERTY SKIP_AUTORCC ON)

     qt_add_executable(myapp ${SOURCES})
