1 # CMakeVerifyManifest.cmake
3 # This script is used to verify that embeded manifests and
4 # side by side manifests for a project match. To run this
5 # script, cd to a directory and run the script with cmake -P.
6 # On the command line you can pass in versions that are OK even
7 # if not found in the .manifest files. For example,
8 # cmake -Dallow_versions=8.0.50608.0 -PCmakeVerifyManifest.cmake
9 # could be used to allow an embeded manifest of 8.0.50608.0
10 # to be used in a project even if that version was not found
11 # in the .manifest file.
13 # This script first recursively globs *.manifest files from
14 # the current directory. Then globs *.exe and *.dll. Each
15 # .exe and .dll is scanned for embeded manifests and the versions
16 # of CRT are compared to those found in the .manifest files
17 # from the first glob.
