[vtkusers] Linker error unresolved external in C++ Builder 6.0

[Walter Cabrera]

Dear David:

I am using CMake with the following configuration:

Source code: C:\VTK
build the binaries: C:\VTK\build

BUILD_EXAMPLES: OFF
BUILD_SHARED_LIBS:OFF
CMAKE_BACKWARDS_COMPATIBILITY: 2.4
CMAKE_BUILD_TYPE: Debug
CMAKE_INSTALL_PREFIX: C:/VTK
VTK_DATA_ROOT: C:/VTK/VTKData
VTK_USE_PARALLEL: ON
VTK_USE_RENDERING: ON
VTK_WRAP_JAVA: OFF
VTK_WRAP_PYTHON: OFF
VTK_WRAP_TCL: OFF

Then I used Borland make(makefile) 
 
I think as you that some library is missing from the link. 

In borland the path to library are placed using Project | Options |
Directories/Conditionals | Library path

Hear is the path C:\VTK\build\bin that contains the VTK libraries builded by
CMake

But the error continues ....

Thank you for everything, very nice

Walter
