This is a known limitation, and it is very hard to fix because Xcode does not provide real custom command support. It only provides "shell script" build phases which we use to drive a Makefile system that has the real custom commands. Currently the projects that CMake generates do not convince Xcode to run the shell script build phase at the right time in all cases. See CMake's BuildDepends test: http://www.cmake.org/cgi-bin/viewcvs.cgi/Tests/BuildDepends/CMakeLists.txt?revision=1.14&root=CMake&view=markup Note the "HELP_XCODE" blocks. -Brad _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
