Thanks Brad, that seems to do it.

Is it intended behavior that if a module is not listed in the
COMPONENTS list of find_package() it will not be available?

For example, with this:

FIND_PACKAGE(VTK REQUIRED COMPONENTS vtkViewsContext2D vtkChartsCore)

my project builds, but with this:

FIND_PACKAGE(VTK REQUIRED COMPONENTS vtkViewsContext2D)

I get:
fatal error: vtkChartXY.h: No such file or directory

The project also builds correctly with only:
FIND_PACKAGE(VTK REQUIRED)

I had assumed that all modules that had been built were available by
default, and adding them to the REQUIRED COMPONENTS list was just
checking for them?
