Summary0014667: MSVC compiler PDB change breaks PCH support (with minimal testcase)
DescriptionThe change http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=42ba1b08 [^] added a compiler switch "/Fd<OBJECT_DIR>".

When using precompiled headers this will now cause errors like:

C:\projects\cmakepch\subdir\test2.cpp(1) : error C2859: c:\projects\cmakepch\build\cmakefiles\test.dir\subdir\vc90.pdb is not the pdb file that was used when this precompiled header was created, recreate the precompiled header.

This occurs for all source files not on the same level as the compiled header object file because msvc is now told to use the pdb in the object directory.

Explicitly setting /Fd does not help because that's overridden by cmake.
Steps To Reproduceplease check the attached minimal testcase.
Additional Informationworks in 2.8.10.2 but not in 2.8.12.

Thanks for the clear report and explanation of this regression.

The problem is that the <OBJECT_DIR> replacement is supposed to point at a single intermediate files directory for all objects in a target but for compile lines it instead points to the directory containing the current object file. This should fix it:

 Replace <OBJECT_DIR> rule placeholder consistently
 http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=03f3b4e7 [^]

With the consistent replacement then the same compiler program database (vc90.pdb) location should be used for all compilations in a single target.
