Including GLSL files in project pane in a QTCreator CMake project

I am working through the OpenGL tutorial here: OpenGL-Tutorial.org, and want to use QTCreator and CMake to build the examples.

Opening the root CMakeLists.txt file opens the project, which then builds/runs correctly (after following instructions on the website), but the fragment and vertex files do not show up in the projects pane. I have tried renaming them to .frag, .vert and .glsl with no effect. If I drag these files from a folder they open in the edit pane with correct syntax highlighting.

How do I get these files to show up in the projects pane?

I am on Ubuntu 20.04 and have tried QTCreator from packages and the newest source on sourceforge.

Another way to include shader files in your Qt project using Cmake is through the CMake command qt5_add_resources. One of the Qt's examples does the same when using qmake. For my application I found it to be more practical to include the shader files as resources.

So, for this, you would have to prepare a resource file, for example, Shaders.qrc, and add there all the shader files you want to use, e.g.:

<RCC>
    <qresource prefix="/">
        <file>Stroke.frag</file>
        <file>Stroke.geom</file>
        <file>Stroke.vert</file>
    </qresource>
</RCC>

Then in the CMakeLists.txt, add the resource file:

qt5_add_resources(SHADER_RSC_ADDED 
    Shaders/Shaders.qrc
)

And add it to the executable (or library): 

add_executable(${PROJECT_NAME}
    ${PROJECT_SRCS}
    ${SHADER_RSC_ADDED}
)

After re-build, the project tree will look like below:

file(GLOB RES_FILES *.frag *.vert *.glsl)

add_executable(exe_name ${RES_FILES} ${C/CPP FILES})

You can add the shader files as other files in the .pro file.

OTHER_FILES += \
    simple.frag \
    simple.vert

Also you should consider using the QT resource management for your shader files. I have recently created a simple OpenGL 3.2 example project in Qt, which also shows how to use the Qt for resource management of shader files. The project is available here: https://github.com/mortennobel/QtOpenGL3.2Core

Warning: the project is only tested on Windows and OS/X.
