Maya 2020. All dev environment vars sets up - path of maya, devkitBase (Autodesk link). Examples compiles and works on 2020 (Autodesk link).

Im not pro in cmake configuration... Could you help? What need to dig?

thanks a lot about this project,
i try it in maya 2018.6,
there is some error about pyside2:
from PySide2.QtCore import QStringListModel

and there some plug-in error when run unit test runner :
RuntimeError: Plug-in, "cmt", was not found on MAYA_PLUG_IN_PATH.

i just want try skinning-converter which show in your youtube video
is the maya 2020 required?

on CentOs using Eigen 3.3.90 trying to compile for maya 2019, I get an error in linearRegressionSolver.cpp invalid initialization of non-const reference of type ‘Eigen::MatrixBase<Eigen::Block<Eigen::Matrix<double, -1, -1>, -1, -1, false> >&’ from an rvalue of type ‘Eigen::MatrixBase<Eigen::Block<Eigen::Matrix<double, -1, -1>, -1, -1, false> >’

as well as it was giving me error that asLong on MDataHandle is depricated and use asInt instead.

I've made a test case for my C++ plugin that uses the maya/MOpenCL* libraries. The usage of those OpenCL libraries is similar to your cvWrap plugin.

I can run the test case interactively (from the Maya GUI), and the test passes. However, if I run the test from Maya's standalone interpreter, the entire interpreter crashes with nothing more than the classic "Fatal Error" error. The crash occurs when my plugin invokes the clCreateBuffer command.

Have you been able to run any tests on your cvWrap plug-in, using the standalone mode? I would try, but I'm not sure what's involved with getting cvWrap to run.

Thanks for any thoughts!

Hello,
I've issues building with CMake:

Any chance you'd know what I'm doing wrong?
Thanks in advance!
