[Insight-users] Re: Errors of Qt + ITK Integration resolved

[Luis Ibanez]

Hi Venkata,

Thanks for letting us know of your success linking
to Qt extended libraries. We will look at merging
your FindQt.cmake file with the one distributed
with CMake.

About your next step, the CUSTOM_COMMAND is the
way to go.

Note that depending on the CMake version you are
using, the syntax of this command may be a bit
different. To make sure use the help-command in
Cmake.  That is, in the command line type:

   cmake --help-command ADD_CUSTOM_COMMAND

that will display the documentation page for
this command in the particular CMakeversion that
you are using.


Since you actually have three commands to execute,
probably the best way to go is to create three
ADD_CUSTOM_COMMAND lines, one correspondin to
each one of your three commands.


For example your command

midl /nologo tmp\obj\release_mt_static\simpleax.idl /tlb
  tmp\obj\release_mt_static\simpleax.tlb


may become something like:


   ADD_CUSTOM_COMMAND(
       OUTPUT   tmp\obj\release_mt_static\simpleax.tlb
       COMMAND  midl
       ARGS /nologo tmp\obj\release_mt_static\simpleax.idl /tlb
            tmp\obj\release_mt_static\simpleax.tlb
       DEPENDS tmp\obj\release_mt_static\simpleax.idl
       )

and the command:

   $(QTDIR)\bin\idc.exe Debug\simpleax.exe /tlb
   tmp\obj\release_mt_static\simpleax.tlb


should become something like


   ADD_CUSTOM_COMMAND(
       COMMAND  $(QTDIR)\bin\idc.exe
       ARGS $(QTDIR)\bin\idc.exe Debug\simpleax.exe /tlb
                tmp\obj\release_mt_static\simpleax.tlb
       DEPENDS  Debug\simpleax.exe
       )


Please let us know if you find any problems
in this second part of converting your project
to CMake.



    Thanks



      Luis
