[Cmake] Possible patches for ITK_WRAP_TCL

[Anton Deguet]

Hello,

I am trying to use ADD_CUSTOM_xxx to run cable.  My plan is to use a 
custom target/command to run cable and then use a regular target to 
compile the generated c++ files.  My problem is that ccmake complains 
about the c++ files which are not yet generated (probably to generate 
the include dependencies).

Here is my cmake code (it's part of a macro I use for a bunch of small 
libraries):

# specify source files.  Now, one per library
SET(${MODULE_NAME}_SOURCES_TCL 
${cis_SOURCE_DIR}/${MODULE_NAME}/wrapping/${MODULE_NAME}Tcl.cpp)

     IF(EXISTS  ${${MODULE_NAME}_SOURCES_TCL})
       # cable rule
       ADD_CUSTOM_TARGET(${MODULE_NAME}TclWrap ALL echo)
       ADD_CUSTOM_COMMAND(SOURCE    ${${MODULE_NAME}_SOURCES_TCL}
                          COMMAND   ${CABLE}
                          ARGS      ${${MODULE_NAME}_SOURCES_TCL}
                          TARGET    ${MODULE_NAME}TclWrap
                          DEPENDS   ${${MODULE_NAME}_SOURCES_TCL}
                          OUTPUT 
${cis_BINARY_DIR}/${MODULE_NAME}TclWrapped.cpp)

       # include for the compilation of cable generated code
       INCLUDE_DIRECTORIES(${TCL_INCLUDE_PATH} ${TK_INCLUDE_PATH} 
${CABLE_INCLUDE_DIR})
       ADD_LIBRARY(${MODULE_NAME}Tcl 
${cis_BINARY_DIR}/${MODULE_NAME}TclWrapped.cpp)
       ADD_DEPENDENCIES(${MODULE_NAME}Tcl ${MODULE_NAME}TclWrap)
       TARGET_LINK_LIBRARIES(${MODULE_NAME}Tcl ${MODULE_NAME} 
${${MODULE_NAME}_DEPENDENCIES} ${CABLE_TCL_LIBRARY})
       INSTALL_TARGETS(/lib ${MODULE_NAME}Tcl)

     ENDIF(EXISTS  ${${MODULE_NAME}_SOURCES_TCL})


When I run cmake, I get the following error (e.g. for MODULE_NAME 
cisCommon):

CMake Error: can not find file 
/home/spine2/anton/devel/cis-2/build/cisCommonTclWrapped.cpp

Is there anyway to tell a target generated with ADD_LIBRARY that the
source file used as an input is the output of a custom command and
therefore might not exist (yet)?
