Compilation related issues, especially on mac m1 devices

Support
1

I am trying to compiling this project on mac m1 pro device , and there are some problems I had encountered.
1
If I want build vtkExternalOpenglRenderWindow, I need to change CMakeCache.txt file to make some option about “External” enable , if I use cmake-gui to enable that option , when I touch “configure” and “generate” button , the entry I had added such like “vtkRenderingExternal” or “VTK_Rendering_External” will miss ,and it do not write into CMakeCache.txt . So the problem is , how do I know how to enable some option and where I can find the result . I can not find the result in vtk-project - build - readme.md.

VTK_MODULE_USE_EXTERNAL_,how do i know the models name ? Is it In cmakelist.txt ?

I had a problem with opengl ,
Here is the output blew :

I notice that the library under thirdparty - glew is compiled , but I think this problem is caused in compile part , I don’t know how to control the build option so this problem I have no idea .
So , I hope some one can answer that question and very very thanks !

These options have nothing to do with vtkExternalOpenGLRenderWindow. You want the VTK_MODULE_ENABLE_VTK_RenderingExternal option (because the class lives in the VTK::RenderingExternal module).

Thanks for your reply .
The option VTK_MODULE_ENABLE_VTK_RenderingExternal I had added in cmake-gui , but after generate , In CMakeCache.txt have only this option ,but no value. So I have to write “ON” to this option ,and after this , the vtkexternalRenderwindow.h can be found .

If you just did cmake -DVTK_MODULE_ENABLE_VTK_RenderingExternal ., that makes sense. It should have been in the cache already though.

Yes , this works , and will build vtk external , but this also has opengl related problem .

This is the output when running a program with vtk :slight_smile:

I need to set external opengl to true and set opengl path after install opengl by brew and then it will have a opengl runtime environment.
