Thanks. I made some style updates and converted it to a patch generated with 'git format-patch'. See attached. I also attached a sample ProjectTargets.json generated for the "COnly" test from our test suite. I'd really like to hear from others on the file format itself. Some comments on the format: * A version number field is needed at the top. * There needs to be support for multi-config generators. Perhaps everything that can be affected by the configuration needs to be inside a list that enumerates all configurations. In single-configuration generators the list would have only one entry for the CMAKE_BUILD_TYPE. In multi-configuration generators it would be all of the CMAKE_CONFIGURATION_TYPES. * Don't IDEs want to know the list of source files so they can be used for editing? I haven't looked at what the Extra generators produce in a while but since they are meant for IDEs they would be a good reference for the information needed. However, AFAIK there is not an extra generator for a multi-config generator. -Brad

Subject: [PATCH] cmake: Add option to generate target metadata for IDEs
Create a CMAKE_OUTPUT_PROJECT_TARGETS option that can be used to enable
generation of a 'ProjectTargets.json' file. Write into the file a JSON
description of the build targets that an IDE might load.
