[Insight-developers] level set/vnl problems on SGI: update

Wed, 16 Apr 2003 08:58:44 -0400

I realize that. The problem is that the test driver for the examples
includes .cxx files. Visual Studio doesn't seem  to follow those depencies.
May there is someway to turn it on?

CMake does not do the depend information for Visual Studio.   This is done
automatically by Visual Studio, and usually works.

an INCLUDE_REGULAR_EXPRESSION to each of the CMakeLists.txt files in
Examples. However, this does not seem to help Visual Studio 6. I think a
forced update on the test driver programs is the only way to get a rebuild.
