<p class=MsoNormal><span lang=EN-US>Anyway the “-DCMAKE_TOOLCHAIN_FILE”

does the makefile for the host system and not the target.<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 the toolchain manament different from
cmake 2.6? I read the documentation twice and they say to do exactly this way.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Any help will be appreciated.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Thanks<o:p></o:p></span></p>
