Subject: [PATCH 3/3] Add external version.cmake.
|
|
|
|
This file is maintained in an external repository. It is only
|
|
included in released versions. For building snapshots of RNP, a fixed
|
|
snapshot of version.cmake is downloaded on demand. To avoid this,
|
|
this patch explicitly provides the file.
