# CMake project that writes Subversion revision information to a header.

# Input variables:
|
|
# FIRST_SOURCE_DIR - First source directory
|
|
# FIRST_NAME - The macro prefix for the first repository's info

# SECOND_SOURCE_DIR - Second source directory (opt)
|
|
# SECOND_NAME - The macro prefix for the second repository's info (opt)
|
|
# HEADER_FILE - The header file to write
|
|
#
|

# The output header will contain macros FIRST_REPOSITORY and FIRST_REVISION,

# and SECOND_REPOSITORY and SECOND_REVISION if requested, where "FIRST" and

# "SECOND" are substituted with the names specified in the input variables.
