What is the proper way to get CMake to build the executable linking against the dylib and be able to run it in the build tree and install tree?</div><div class="gmail_extra"><br clear="all"><div>Izaak Beekman<br>===================================<br>(301)244-9367<br>UMD-CP Visiting Graduate Student<br>Aerospace Engineering<br><a href="mailto:ibeekman@umiacs.umd.edu" target="_blank" data-mce-href="mailto:ibeekman@umiacs.umd.edu">ibeekman@umiacs.umd.edu</a><br> <a href="mailto:ibeekman@umd.edu" target="_blank" data-mce-href="mailto:ibeekman@umd.edu">ibeekman@umd.edu</a></div><br><div><br></div><div class="gmail_quote">On Sat, May 3, 2014 at 10:54 AM, Dan Kegel <span dir="ltr"><<a href="mailto:dank@kegel.com" target="_blank" data-mce-href="mailto:dank@kegel.com">dank@kegel.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex" data-mce-style="margin: 0 0 0 .8ex; border-left: 1px #ccc solid; padding-left: 1ex;"><div class="">On Sat, May 3, 2014 at 7:17 AM, <<a href="mailto:clinton@elemtech.com" target="_blank" data-mce-href="mailto:clinton@elemtech.com">clinton@elemtech.com</a>> wrote:<br> > Use at least CMake 2.8.12 and in your library project add this:<br> > set(CMAKE_MACOSX_RPATH 1)<br></div>> ...<br><div class="">> For more details:<br> > <a href="http://www.kitware.com/blog/home/post/510" target="_blank" data-mce-href="http://www.kitware.com/blog/home/post/510">http://www.kitware.com/blog/home/post/510</a><br> <br></div>What he said.
