[CMake] Is it possible to patch a make project with CMakeLists.txt, through external_project_add?

[Micha Hergarden]

Hello Mike,

The externalproject_add command has an option that might do what you want:
https://cmake.org/cmake/help/v3.8/module/ExternalProject.html

See:

|PATCH_COMMAND <cmd>...|
    Command to patch downloaded source

Regards,
Micha
