I have done something similar to the following: add_custom_command(OUTPUT foo.ext) add_executable(foo foo2.ext) add_custom_target(foo_custom DEPENDS foo.ext) set_source_files_properties(foo.ext PROPERTIES GENERATED TRUE) add_dependencies(foo foo_custom) The above will not cause a dependency of foo on foo.ext
You don't need a separate custom target to generate a file if it will be used by one target in the same directory. The code add_custom_command(OUTPUT foo.ext ...) add_executable(foo foo.ext ...) will cause it to be generated prior to compiling the sources in "foo". Even so, your example works for me: $ cat ../CMakeLists.txt cmake_minimum_required(VERSION 2.6) project(FOO C) add_custom_command(OUTPUT foo.ext COMMAND touch foo.ext) add_executable(foo foo.c) add_custom_target(foo_custom DEPENDS foo.ext) set_source_files_properties(foo.ext PROPERTIES GENERATED TRUE) # not necessary add_dependencies(foo foo_custom) $ cmake .. -- The C compiler identification is GNU -- Check for working C compiler: /usr/bin/gcc -- Check for working C compiler: /usr/bin/gcc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Configuring done -- Generating done $ make foo Scanning dependencies of target foo_custom [ 50%] Generating foo.ext [ 50%] Built target foo_custom Scanning dependencies of target foo [100%] Building C object CMakeFiles/foo.dir/foo.c.o Linking C executable foo [100%] Built target foo -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
