Hey Reza!
Thank you so much for your answer, I really appreciate it!
So I tried to do as you said and rework a little my cmake files build. I
added pluginEntry.cmake
It seems like OpenGL is there (I haven't tested it yet in VisualStudio, by
I can see in terminal that there was an ouput that OpenGl was found (I also
looked a little into pluginEntry.cmake and there find_opengl part).
Can I ask you, how are you adding Qt dependencies to your project in CMake?
previously I was able to make it work, but my approach was a bit messy,
basically almost half was done manually in Visual Studio. I understand that
it is incorrect and there is shoud be CMake way to do that.
I tried several things, for example in devkit there cmake folder with all
additional Qt folders which have Qt cmake files.
My initial thought was that I just need to include those cmake's into my
build and after that linking will work as expected. I even wrote a tiny
cmake script which adds each qt folder as module folder into my CMake build
but it does not helped. I have this error, in which it seems that Qt
dependencied are not there:
"""
CMake Error at src/CMakeLists.txt:30 (find_package):
By not providing "FindQt5.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Qt5", but
CMake did not find one.
Could not find a package configuration file provided by "Qt5" with any of
the following names:
Qt5Config.cmake
qt5-config.cmake
Add the installation prefix of "Qt5" to CMAKE_PREFIX_PATH or set "Qt5_DIR"
to a directory containing one of the above files. If "Qt5" provides a
separate development package or SDK, be sure it has been installed.
-- Configuring incomplete, errors occurred!"""
I also tried to use FindMaya_Qt.cmake (this file I found in AutodeskUSD
repository, it also does not working, but gives me slightly different error.
A little information about my project.
I launched it just as you said:
