[vtk-developers] Errors in building VTKExamples in today's CVS

[Bill Lorensen]

Brad,

I added the proect(VTKExamples) in the Examples/CMakeLists.txt file.

Also added the
IF(NOT VTK_BINARY_DIR)
 FIND_PACKAGE(VTK REQUIRED)
ENDIF(NOT VTK_BINARY_DIR)

Then ran cmake with source: VTK/Examples with the bin pointing to a
separate build tree.

I generated a solution file and I was able to build it in Visual Studio.

Also ran cmake with source: Examples/Medical/Cxx

I generated a solution file and I was able to build it in Visual Studio.

So far so good,

Bill
