How do I add a different compile flag to just one file inside a project?
I'm using MSVC.
Specifically I want to be able to use pre-compiled headers and it requires one file to have the flags to create the pre-compiled headers, while the rest have the flags to just use the pre-compiled headers.

Hi,
The precompiled headers are AFAIK not supported in TheIDE. You can in theory use a custom build step for this. Just create a dummy file, with some distinct extension (anything goes, eg. cppforheaders  ) and make it include the headers to be precompiled. Then you can set the the 'cl.exe -Yc"header.pch" ... ' command as a custom build step (see this page for details) for files with your special extension (you can do this in Poject -> Custom build steps). The other files can then get the -Yu parameter by adding it as an additional compiler option to your package in Package manager.
Disclaimer: I never used precompiled headers nor MSVC, so I might be partially all completely wrong 
Best regards,
Honza
