How do I fix "Unknown CMake command 'wut_create_rpx'"?

[nulcow]

Here is my CMake file (slightly modified from a sample application):

cmake_minimum_required(VERSION 3.2)
set(CMAKE_TOOLCHAIN_FILE /opt/devkitpro/wut/share/wut.toolchain.cmake)


project(helloworld C)
include("/opt/devkitpro/cmake/WiiU.cmake" REQUIRED) # used to be "/opt/devkitpro/wut/share/wut.cmake" but the software told me to not use that.


add_executable(helloworld
    main.c)


target_compile_options(helloworld PRIVATE -Wall)


wut_create_rpx(helloworld) # problem starts here

I have everything I need installed, and the directory structure is set up correctly.

Firstly, fix your CMakeLists.txt:

cmake_minimum_required(VERSION 3.20)
project(helloworld C)

add_executable(${PROJECT_NAME} main.c)
target_compile_options(${PROJECT_NAME} PRIVATE -Wall)
wut_create_rpx(${PROJECT_NAME})

That's all that is necessary, the other lines will just get in your way.

Then:

cmake -B build -S . -GNinja -DCMAKE_TOOLCHAIN_FILE=/opt/devkitpro/cmake/WiiU.cmake
ninja -C build

Everything DevKitPro related was always a mess and will probably always be, examples of how to use the CMake system properly should have been there for ages. As a note, you don't really need to use Linux or MSYS2 for that matter, you can just mod a thing or two (depending on the platform) and the CMake tool chain will work out of the box on Windows in whatever IDE you use, no Linux tools required. But they put Linux only stuff there on purpose, because who knows.

Good luck on your development endeavors!~
