In tdelibs/kdoctools/CMakeLists.txt, I added the following: include( ConfigureChecks.cmake ) In that same directory I created two files: ConfigureChecks.cmake update-entities.sh The update-entities.sh script never executes. The script works --- I can run manually just fine. ConfigureChecks.cmake looks like this: ################################################# # # (C) 2012 Trinity Project # # Improvements and feedback are welcome # # This file is released under GPL >= 2 # ################################################# configure_file( ${CMAKE_SOURCE_DIR}/kdoctools/update-entities.sh ${CMAKE_SOURCE_DIR}/kdoctools/update-entities @ONLY ) set( UPDATE_SCRIPT "${CMAKE_SOURCE_DIR}/kdoctools/update-entities" ) set( TDEVERSION_FILE "${CMAKE_SOURCE_DIR}/tdecore/tdeversion.h" ) set( ENTITIES_FILE "${CMAKE_SOURCE_DIR}/kdoctools/customization/entities/general.entities" ) if( NOT EXISTS ${UPDATE_SCRIPT} ) tde_message_fatal( "${UPDATE_SCRIPT} not found!\n Check your sources." ) endif( ) if( NOT EXISTS ${TDEVERSION_FILE} ) tde_message_fatal( "${TDEVERSION_FILE} not found!\n Check your sources." ) endif( ) if( NOT EXISTS ${ENTITIES_FILE} ) tde_message_fatal( "${ENTITIES_FILE} not found!\n Check your sources." ) endif( ) execute_process( COMMAND "bash ${UPDATE_SCRIPT}" RESULT_VARIABLE _result OUTPUT_STRIP_TRAILING_WHITESPACE ) if( _result ) tde_message_fatal( "Unable to update ${ENTITIES_FILE}!\n " ) else( ) message( STATUS "Updated ${ENTITIES_FILE}." ) endif( )
