Source/ThirdParty/libsysprof-capture/README.WebKit

This directory contains a copy of libsysprof-capture from the
official Sysprof repository.

  - URL: https://gitlab.gnome.org/GNOME/sysprof

The simplest way of updating its contents is to re-create the directory
from scratch, and restoring the needed files with Git. Example commands:

  rm -rf Source/ThirdParty/libsysprof-capture
  cp -ar ../path/to/sysprof/src/libsysprof-capture Source/ThirdParty/
  git checkout -- \
      Source/ThirdParty/libsysprof-capture/README.WebKit \
      Source/ThirdParty/libsysprof-capture/CMakeLists.txt \
      Source/ThirdParty/libsysprof-capture/include/config.h
  git rm -r Source/ThirdParty/libsysprof-capture/tests
  git add -A Source/ThirdParty/libsysprof-capture

The sysprof-version.h file has to be generated to be included in this
directory, instead of including only the .h.in template. To obtain it,
run the following at the Sysprof source tree:

  meson setup build \
    -Dhelp=false -Dsysprofd=none -Dlibsysprof=false \
    -Dtools=false -Dtests=false -Dexamples=false -Dgtk=false
  cp build/src/libsysprof-capture/sysprof-version.h \
    ../path/to/WebKit/Source/ThirdParty/libsysprof-capture/

Then check whether the updated sources require any changes to the CMake
build system, and update the Sysprof commit identifier and tag in this
file.
