qt_add_resources error

abdelmaegd

I'm trying to use CMake macro qt_add_resources, and add qrc file that has comments, and it seems this makes generate rules including the comments add dependencies.

Example:
resourcesq.qrc

<!-- WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING
     +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
     my quoted comment is here "<file>"s after quoted comment
     +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
-->
<RCC>
    <qresource prefix="/guiResources">
       <file>fnGettingStarted.txt</file>
<!-- EXAMPLE OF USING FILE ALIAS
       <file alias="bang.svg">images/bangCircleYellow.svg</file>
-->
    </qresource>
</RCC>

CMakeLists.txt

cmake_minimum_required(VERSION 3.18)
project(hello_qrc VERSION 1.0)

find_package(Qt5 REQUIRED COMPONENTS Core Gui)

qt_add_resources(SOURCES resources.qrc)

add_library(lib ${SOURCES})

This is the error during cmake --build build -t lib

ninja: error: '/home/abdelmak/sandbox/cmake/rcc/"s after quoted comment     +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++-->/home/abdelmak/sandbox/cmake/rcc/fnGettingStarted.txt', needed by '/home/abdelmak/sandbox/cmake/rcc/build/qrc_resources.cpp', missing and no known rule to make it

If I remove the upper comment and keep the comment at the end, it errors also with

ninja: error: '/home/abdelmak/sandbox/cmake/rcc/images/bangCircleYellow.svg', needed by '/home/abdelmak/sandbox/cmake/rcc/build/qrc_resources.cpp', missing and no known rule to make it

Is this issue in the macro itself ?

No since the macro only invokes cmake and rcc so you should create a cmake bug report but I doubt this will get high priority - even you're correct a qrc file is not meant to be modifed by anything else but the Qt tools.
