|
|
# Inputs:
|
||
|
|
# - from_version: Source schema version (changelog input side).
|

|
|
# - to_version: Target schema version (header/changelog output side).
|
||
|
|
# - CPPBESSOT_ODB_EXECUTABLE: Path to `odb` compiler.
|
||
|
|
# Outputs:
|
||
|
|
# - CMake target: `db_gen_migrations` (EXCLUDE_FROM_ALL).
|
||
|
