<!-- Magic pseudo-target that makes object filenames relative to a given directory <!-- Add ObjectFileName for ClCompile items that need to be placed in subdirs
for linking to work, for projects with same-named files in separate dirs.
First define its relation to the system build targets: It must run as part of the
"compile inputs" section, but before all the system things. The system things here To use this feature, add a InputRelativeSourceDir metadata to ClCompile for
include testing whether multiple inputs might have identical outputs, which will a project.
produce a warning which we don't want.
Then define the target, make it depend on all ClCompile items, and have a fake
output that can never be a valid filename (due to pipe character). Instead have
the output name depend on the two variables involved in how the ObjectFileName
is determined: The specified InputRelativeSourceDir, and the actual RelativeDir
for the items.
This will cause MSBuild to batch the items as appropriate.
To use this feature, add a InputRelativeSourceDir metadata to ClCompile for
a project.
