[CMake] [DKIM: Failed] Troubles with ExternalProject_Add and PATCH_COMMAND

[Marcel Loose]

Hi Steven,

When you run patch manually, do you then supply the same absolute paths?
Looking at the patch file I noticed that it contains a relative path. So
maybe you should cd to
${CMAKE_BINARY_DIR}/boost/src/external_boost/project-config.jam before
running the patch command.

Cheers,
Marcel.
