What exactly are you wanting to do? meson has --pkg-config-path and --build.pkg-config-path, which let you set additions paths for pkg-config to search in, it also has --cmake-prefix-path and --build.cmake-prefix-path which set the CMAKE_PREFIX_PATH env variable when using cmake as a dependency finder.

We I am trying to fixes curses detection, when I detecting whe methd=system, I need to know a list of PREFIX path to relative to find the corresponding package. For some package, they comes without pkg-config, just bin/include/lib directory, I need to find them with custom method=system. And this need a CMAKE_PREFIX_PATH directory, that's what I am talking about, and In meson, CMAKE_PREFIX_PATH are transfered to cmake directly, meson didn't use of it

I think what you're looking for is the sys_root property in the cross/native file?

And we won't pass sys_root parameter to meson. And even with cross, we still need a list of sys_root , not a single sys_root
