CMake Unknown Command plasma_install_package

Hey there I'm trying to start developing some KDE Plasma 5 widgets however whenever I attempt to build the tutorial widget I get the following error:

mathew@:hello_world_widget:-> cmake CMakeLists.txt 
CMake Error at CMakeLists.txt:1 (plasma_install_package):
  Unknown CMake command "plasma_install_package".


CMake Warning (dev) in CMakeLists.txt:
  No cmake_minimum_required command is present.  A line of code such as

    cmake_minimum_required(VERSION 3.1)

  should be added at the top of the file.  The version specified may be lower
  if you wish to support older CMake versions for this project.  For more
  information run "cmake --help-policy CMP0000".
This warning is for project developers.  Use -Wno-dev to suppress it.

-- Configuring incomplete, errors occurred!
See also "/home/mathew/projects/hello_world_widget/CMakeFiles/CMakeOutput.log".
mathew@:hello_world_widget:-> 

I have the extra-cmake-modules-git and cmake-git packages installed from the aur. I did attempt to use the cmake and extra-cmake-modules packages from the official repositories and it gave the same error. I googled for quite some time but could find no answers.

Re: CMake Unknown Command plasma_install_package

I have the same problem. It look like bug to me because I had downloaded PKGBUILD from official plasma-nm 5.1.2-1 package, tried to build this and I had the same message. I don't know in which package this CMake command "plasma_install_package" should be, so it's possible that something is missing in my system... Someone can help?

Werid... Maybe some extra configuration of cmake is needed?

Re: CMake Unknown Command plasma_install_package

I got the same here...

  Unknown CMake command "plasma_install_package".

You do not have any ideas on how to solve this problem?

Re: CMake Unknown Command plasma_install_package

This is just because the tutorial is shit.

From reading the top level CMakeLists.txt of of the plasma-workspace source and seeing that Kf5Plasma needs to be included with "grep -R plasma_install_package /usr/lib/cmake/" and some trial and error, this is an actual minimal CMakeLists.txt:

project(YOURPROJECT)
cmake_minimum_required(VERSION 2.8.12 FATAL_ERROR)

find_package(ECM 0.0.11 REQUIRED NO_MODULE)
set(CMAKE_MODULE_PATH ${ECM_MODULE_PATH} ${ECM_KDE_MODULE_DIR})
find_package(KF5Plasma)

plasma_install_package(YOURPROJECT org.kde.YOURPROJECT plasma/plasmoids applet)

Re: CMake Unknown Command plasma_install_package

There were two almost identical versions of the tutorial, one with a corrected CMakeLists.txt, the other was incomplete. I have meanwhile tried to fix the CMakeLists.txt file at https://techbase.kde.org/Development/Tu … ingStarted.

As for the error, even if the KF5Plasma cmake file does locate the ECM package, it does not modify the CMAKE_MODULE_PATH. Could be a bug / design decision.
