vtk pkgconfig file not installed?

[pauldmccarthy]

Howdy,

The vtk pkgconfig file is not installed as part of this reecipe - this makes it difficult to compile projects against a conda-forge-installed version of VTK.

The -DINSTALL_PKGCONFIG_DIR:PATH=$PKG_CONFIG_PATH flag was a part of the very first version of this recipe, but was removed almost immediately in this commit: 803b65b

Is there any reason for this, and is there any possibility of having it added back in?

Thanks!
