<p class=MsoNormal><span lang=EN-US>Hello,<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>using CMake 2.6.4 to build one of our
projects an error occurred due to the repeated usage of add_subdirectory on the
same path.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>In former versions of CMake the repeated
usage was accepted and worked fine.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>The referenced project has the following scripting
steps:<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>1. The source tree is traversed to gather
information (+configure snippet files) and compile it in a setup file. This
information can be contributed arbitrary by any sub part of the project.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>2. The source tree is traversed a second
time to generate the visual studio project files. This is the “normal”
cmake run that adds external projects, libraries, executables etc.. This run needs
the setup file compiled by the first run to successfully create all VS projects.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Right now the scripts discriminate between
both modi/runs by a CMake variable. The gathering of information is needed
because some VS projects must be created by external tools (QMake, MeVis
Toolrunner) and CMake only triggers the creation and adds the targets
afterwards.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Is there any possibility to access
subdirectories and process cmakelists.txt in the same manner like
add_subdirectory without provoking this error. Or is there a policy (planed) that
controls this special behavior? Looking in the documentation I have not found
such a policy.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Any suitable solution is appreciated because
right now the dilemma seems only to be solvable either by discarding a lot of
generalization that helps to keep this project easy to maintain and to extend
or by sticking to CMake 2.6.3, which is not preferable on the long run. Thanks.<o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-US>Kind Regards,<o:p></o:p></span></p>
