Summary

0011880: For Visual Studio 2010, adding /Y- (don't use precompiled headers) to a source file's properties does not remove the /Yu flag

Description

Adding the /Y- flag (don't use precompiled headers) does not remove the /Yu flag (use precompiled headers), so when viewed in Visual Studio, such a file appears to still use precompiled headers. However, the command line shows that /Y- is added and overrides /Yu.

Steps To Reproduce

Consider the following:

--- cut here ---
if (MSVC)
    set_target_properties(FooProj PROPERTIES COMPILE_FLAGS "/YuFoo.h")
    set_source_files_properties(Foo.cpp PROPERTIES COMPILE_FLAGS "/YcFoo.h")
    set_source_files_properties(FooNotUsingPch.cpp PROPERTIES COMPILE_FLAGS "/Y-")
endif ()
--- cut here ---

Adding the /Y- flag does not remove the /Yu flag, so when viewed in Visual Studio, FooNotUsingPch.cpp appears to still use precompiled headers. However, the command line shows that /Y- is added and overrides it.

Additional Information

This only appears to affect how the project appears in the IDE.

/Y- is not listed in cmVS10CLFlagTable.h like /Yc and /Yu are. The option for "Not Using Precompiled Headers" is "", which in this case may not be sufficient.

Notes
(0030232) David Cole (manager) 2012-08-11 11:09	Sending old, never assigned issues to the backlog. (The age of the bug, plus the fact that it's never been assigned to anyone means that nobody is actively working on it...) If an issue you care about is sent to the backlog when you feel it should have been addressed in a different manner, please bring it up on the CMake mailing list for discussion. Sign up for the mailing list here, if you're not already on it: http://www.cmake.org/mailman/listinfo/cmake [^] It's easy to re-activate a bug here if you can find a CMake developer who has the bandwidth to take it on, and ferry a fix through to our 'next' branch for dashboard testing.
