Description

When updating OpenCV, then doing an incremental build, sometimes I get failures related to precompiled headers. One recent example is revision 5253. I have a fully built OpenCV at rev 5252, then do svn update to 5253 (which changes include/opencv2/core/core.hpp), then do an incremental build.

There is no problem to build the core library (there precomp.cpp is recompiled), but there is a problem in the imgproc library. Here precomp.cpp is not recompiled, although it should have been, due to the include chain: imgproc/precomp.cpp <= imgproc/precomp.hpp <= imgproc/imgproc.hpp <= core/core.hpp

For some reason this dependency does not seem to be recognized by the build system.

WinXP, VS2005, CMake 2.8

Could not reproduce the issue. Precompiled headers was rebuilt as expected after touching the core.hpp.

Tried this with trunk r7673, Release configuration.
- Windows 7 x64
- MSVS 2005 SP2
- cmake 2.8.3 (run without any extra options)

Please, reopen the ticket if you have a reproducible scenario.
