[vtkusers] Getting Started Questions

[Mike Jackson]

Couple ideas, but they may be way off for Linux.
   First, use "ccmake" to run the "gui" version of cmake. After that  
launches press the "t" key to get the advanced view. Scroll down the  
list and look for VTK_USE_RPATH (I think that is it) and turn that ON.  
This allows running VTK apps from the build directory but will stop  
any type of actual "install" of vtk. This may solve the library  
loading issues.

    Still in ccmake, there is an option to "BUILD_TESTING". Turn this  
on or make sure it was ON. Type "c" to configure again. Type "g" to  
generate new makefiles and exit ccmake.
   Recompile vtk. If you have a multi-core/multi-processor system use  
"make -j2" to help speed up the recompile.
   After the compilation reaches 100% you can do a "make test" which  
will run all the tests and report any errors. Simply watch the output  
for any tests that fail. If they all pass then you have a good build.

Hope some of that helps
