# CMake Module to generate Source Link JSON for the MSVC compiler
|
|
#
|
|
# Microsoft defines Source Link as the following:
|
|
#
|
|
# > Source Link is a developer productivity feature that allows unique
|
|
# > information about an assembly's original source code to be embedded in its
|
|
# > PDB during compilation.
|
|
# https://github.com/dotnet/designs/blob/master/accepted/diagnostics/source-link.md
|
|
#
|
|
# Specifically, this script will embedded information into the PDB of where to
|
|
# download the source code from. This will allow developers to use the PDB without
|
|
# the source located on disk.
|
|
#
|
|
# This script currently only works with GitHub but could be extended to support
|
|
# other source control servers. Any server which hosts their code as raw source
|
|
# over HTTP should work.
