A line of code such as<br><br> cmake_minimum_required(VERSION 2.8)<br><br> should be added at the top of the file. The version specified may be lower<br> if you wish to support older CMake versions for this project. For more<br> information run "cmake --help-policy CMP0000".<br>This warning is for project developers. Use -Wno-dev to suppress it.<br><br>-- Configuring incomplete, errors occurred!<br><br></div>It seems like list_subdirectories macro cannot be found by cmake. How can I fix this?<br>When trying to build cameraserver module separately, I got the following errors:<br><br>[100%] Building CXX object CMakeFiles/cameraserver.dir/cameraserver.o<br>In file included from /home/tarciso/workspaces/gsoc-workspace/JdeRobot/trunk/src/stable/components/cameraserver/cameraserver.cpp:27:0:<br>/usr/local/include/jderobot/camera.h:39:19: fatal error: image.h: No such file or directory<br>compilation terminated.<br>make[2]: *** [CMakeFiles/cameraserver.dir/cameraserver.o] Error 1<br>make[1]: *** [CMakeFiles/cameraserver.dir/all] Error 2<br>make: *** [all] Error 2<br><br>[100%] Building CXX object CMakeFiles/cameraserver.dir/cameraserver.o<br>In file included from /usr/local/include/jderobot/camera.h:39:0,<br> from /home/tarciso/workspaces/gsoc-workspace/JdeRobot/trunk/src/stable/components/cameraserver/cameraserver.cpp:27:<br>/usr/local/include/jderobot/image.h:39:20: fatal error: common.h: No such file or directory<br>compilation terminated.<br>make[2]: *** [CMakeFiles/cameraserver.dir/cameraserver.o] Error 1<br>make[1]: *** [CMakeFiles/cameraserver.dir/all] Error 2<br>make: *** [all] Error 2<br><br>[100%] Building CXX object CMakeFiles/cameraserver.dir/cameraserver.o<br>In file included from /usr/local/include/jderobot/image.h:39:0,<br> from /usr/local/include/jderobot/camera.h:39,<br> from /home/tarciso/workspaces/gsoc-workspace/JdeRobot/trunk/src/stable/components/cameraserver/cameraserver.cpp:27:<br>/usr/local/include/jderobot/common.h:32:22: fatal error: datetime.h: No such file or directory<br>compilation terminated.<br>make[2]: *** [CMakeFiles/cameraserver.dir/cameraserver.o] Error 1<br>make[1]: *** [CMakeFiles/cameraserver.dir/all] Error 2<br>make: *** [all] Error 2<br><br></div>The referred files exist and are in the same directory as the source header file, however for some reason the compiler cannot find them.
