The same goes for Windows and for pip install PyStasm. Found this comment by millpond here, possible solution?

stasm is looking for opencv header files in the MSVC Include dirs.

Typically you can grab the source for a package and copy the \Include dir to the MSVC Include path, and it should work. Though not here. Stasm eventually wants opencv_modules.hpp which is only generated after a proper compilation (not a typical install). Which does not look possible without a decent working knowledge of Visual Studio, or VSC.

Hint: Symlink MSVC Include and Lib dirs to an easy to get to location to allow easier access.
