VS_SOURCE_SETTINGS_<tool>

New in version 3.18.

Set any item metadata on all non-built files that use <tool>.

Takes a list of Key=Value pairs. Tells the Visual Studio generator to set Key to Value as item metadata on all non-built files that use <tool>.

For example:

set_property(TARGET main PROPERTY VS_SOURCE_SETTINGS_FXCompile "Key=Value" "Key2=Value2")

will set Key to Value and Key2 to Value2 for all non-built files that use FXCompile.

Generator expressions are supported.
