Hello, I have a custom target which runs a command to generate a C source file say test1.c
ADD_CUSTOM_TARGET(TestGen ALL COMMAND genExec ${PROJECT_SOURCE_DIR}/Main.java DEPENDS ${PROJECT_SOURCE_DIR}/Main.java ) And I have a custom command that moves the generated *test1.c * to a new directory inside the build directory. ADD_CUSTOM_COMMAND( TARGET TestGen POST_BUILD COMMAND mv ARGS ${PROJECT_BINARY_DIR}/test1.c ${PROJECT_BINARY_DIR}/tests/ ) Each time I run make, the custom target is run (since custom targets are always out-of-date). But I want to avoid moving the new test1.c generated each time if build/test1.c is the same as build/tests/test1.c since there are other targets like add_executable and add_library later in the CMakelists file that are re-built each time since they depend on test1.c I tried cmake -E compare_files inside execute_process, but it would not be executed before the custom command. I tried cmake -E compare_files inside a custom command as well, but that would give an error and halt the make process if the files differ. I want to avoid re-building later targets that depend on test1.c. Thanks Ajay
