Project->Properties->Configuration Properties->Linker->General->Enable Incremental Linking->No(/INCREMENTAL:NO)
This is probably a VS10 specific thing that the CMake config doesn't know about yet. I noticed that the release version of DCMTK doesn't have this problem.
That fixed almost all of the apps. There were still a couple that couldn't resolve the _main symbol. Some investigation showed that the source file containing the main() function was omitted from the project by CMake. I added it to the app's project with
Project->Add Existing Item...
then browse to the <module>\apps directory and select the <App Name>.cc file. Rebuild and it should be golden.
Hope this saves somebody some time and head-scratching.
