Answer 1

This is how we added code generation for ecpg in cmake.

set( PGSQL_ARG "input_file.pgc" )
add_custom_command( OUTPUT ${CMAKE_CURRENT_SOURCE_DIR}/output_file.c
                    COMMAND ${PGSQL_CMD} ${PGSQL_ARG}
                    DEPENDS ${CMAKE_CURRENT_SOURCE_DIR}/input_file.pgc
                    WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} )
