Hi, I am trying to generate file that depends on a set of files that can change throughout different make invocations.
To understand it better, let's show you the code: ----------- cmake_minimum_required(VERSION 2.8) project(demo-one C) add_custom_command( OUTPUT "${CMAKE_BINARY_DIR}/generated.c" COMMAND generate -o "${CMAKE_BINARY_DIR}/generated.c" DEPENDS "$(shell generate-dependencies-list)" COMMENT "Generating generated.c" ) add_executable(main main.c "${CMAKE_BINARY_DIR}/generated.c") ----------- So, I want to generate the file generated.c with the "generate" command and this files needs to be regenerated when the files specified by "generated-dependencies-list" command changes. As you may notice, "generated-dependencies-list" can generate different set of files throughout different make invocations, so is not feasible to get the result of "generated-dependencies-list" at configure time to then pass the result to add_custom_command. Actually the above code somewhat works, but it looks like a hack that will only work for Makefile backend, also the make rule doesn't look as what I'm expecting, after all, it's a hack: generated.c: ../$(shell\ generate-dependencies-list) Has CMake any feature to achieve this? Basically, I want this rule or something to get the same result: generated.c: $(shell generate-dependencies-list) -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
