If builds KF5 project with current KF5AuthMacros.cmake, then occured this error: CMake Error at /lib64/cmake/KF5Auth/KF5AuthMacros.cmake:76 (add_custom_target): The target name "actions for org.freedesktop.auth.cpufrequtility" is reserved or not valid for certain CMake features, such as generator expressions, and may result in undefined behavior. I'm changed target Name "actions for ${HELPER_ID}" to "actions_for_${HELPER_ID}" (with underscores), then project is built. Maybe this related with target naming: http://www.cmake.org/cmake/help/v3.0/command/add_custom_target.html Reproducible: Always Steps to Reproduce: Project for example: https://github.com/F1ash/kf5-cpufrequtility 1. build as is 2. edit /lib{?64}/cmake/KF5AuthMacros.cmake line 76 to add_custom_target("actions_for_${HELPER_ID}" ALL DEPENDS ${_output}) 3. build again Actual Results: after step1 occured error: CMake Error at /lib64/cmake/KF5Auth/KF5AuthMacros.cmake:76 (add_custom_target): The target name "actions for org.freedesktop.auth.cpufrequtility" is reserved or not valid for certain CMake features, such as generator expressions, and may result in undefined behavior. after step2,3 -- error isn't appear Expected Results: building without this error
This error only occurs if one uses: cmake_minimum_required(VERSION 3.2) if replaced by cmake_minimum_required(VERSION 2.8.12) the error is replaced by a warning: CMake Warning (dev) at /lib64/cmake/KF5Auth/KF5AuthMacros.cmake:76 (add_custom_target): Policy CMP0037 is not set: Target names should not be reserved and should match a validity pattern. Run "cmake --help-policy CMP0037" for policy details. Use the cmake_policy command to set the policy and suppress this warning. The target name "actions for org.freedesktop.auth.cpufrequtility" is reserved or not valid for certain CMake features, such as generator expressions, and may result in undefined behavior. Call Stack (most recent call first): src/helper/CMakeLists.txt:22 (kauth_install_actions) This warning is for project developers. Use -Wno-dev to suppress it.
with: cmake_minimum_required(VERSION 2.8.12) cmake_policy(SET CMP0037 OLD) the problem disappears.
I guess you'd also get away with: cmake_minimum_required(VERSION 3.2) cmake_policy(SET CMP0037 OLD) Still, KAuth should not be requiring a CMake policy to be set to OLD.
Actions for helper id is now a comment, I'm guessing that has solved this problem.
