[CMake] get version number from debian/changelog using cmake?

[Christopher Lang]

Hi,

thanks for the hint. Here is what I made of it (for cmake 2.4). Could be 
helpful to somebody else...


# read debian/changelog and parse the version/build number
FILE (READ "${CMAKE_CURRENT_SOURCE_DIR}/debian/changelog" DEBCHANGELOG)

STRING (REGEX MATCH "([0-9]+\\.[0-9]+\\.[0-9]+-[0-9]+)" 
DEBFULLVERSION "${DEBCHANGELOG}")
STRING (REGEX MATCH "([0-9]+\\.[0-9]+)" DEBMAINVERSION "${DEBFULLVERSION}")

SET(DEBFULLVERSION ${DEBFULLVERSION} CACHE INTERNAL "Full package version." 
FORCE)
SET(DEBMAINVERSION ${DEBMAINVERSION} CACHE INTERNAL "Main package version." 
FORCE)

# needs to be AFTER the SET commands for version number...
CONFIGURE_FILE(${CMAKE_CURRENT_SOURCE_DIR}/config.h.cmake 
${CMAKE_CURRENT_BINARY_DIR}/config.h)


cheers
Chris
