# .. command:: vcpkg_fixup_cmake_targets
#
# Transforms all /debug/share/<port>/*targets-debug.cmake files and move them to /share/<port>.
# Removes all /debug/share/<port>/*targets.cmake and /debug/share/<port>/*config.cmake
#
# Transforms all references matching /bin/*.exe to /tools/<port>/*.exe on Windows
# Transforms all references matching /bin/* to /tools/<port>/* on other platforms
#
# Fixes ${_IMPORT_PREFIX} in auto generated targets to be one folder deeper.
# Replaces ${CURRENT_INSTALLED_DIR} with ${_IMPORT_PREFIX} in configs/targets.
#
# ::
# vcpkg_fixup_cmake_targets([CONFIG_PATH <config_path>])
#
# ``CONFIG_PATH``
# *.cmake files subdirectory (like "lib/cmake/${PORT}").
#
# Example usage:
# vcpkg_fixup_cmake_targets(CONFIG_PATH "lib/cmake/myPort")
