[yocto] Native build tools question

[Marc Ferland]

Hi,

I'm currently writing a recipe for the visualization toolkit (vtk).

To compile, this library invokes executables that are generated on-the-fly
by the compilation process (a little bit like Qt and qmake).

The path to these executables can be specified to cmake when building vtk.
So far I was able to make it work by hard-coding this "tools" directory in
my recipe to a path on my local machine. It works, but it is not very
portable.

What's the official way to handle such libraries?

Should I first do a native build, then use this native build directory when
cross-compiling? If so, is there any examples I should look into?

Regards,

Marc
