I have a file called version.cmake that my root CMakeLists.txt includes. There is only a single line in this file:
set( BUILD_VERSION 1.2.3.4 CACHE STRING "Version of the product" ) I have two scenarios where this version number setting needs to work slightly differently from a CMake perspective: 1. Our CI build server does a fresh clone of our repo, and generates from scratch. It sometimes needs to override the version number from the command line via arguments. So it will do: -D BUILD_VERSION=99.99.1.2 This works since it's a cache variable. In fact, the current solution ONLY works well for this scenario (since it will allow overriding from command line, but also allow the file to set the value if it is not specified as a -D argument). 2. Local work machine builds. Local builds never override using -D, they always use what is in the version.cmake file. However, because it's a cache variable and I'm not using FORCE with set(), it never updates if I change the version and push it to origin. This is the missing requirement: it needs to update when the number (value) changes in version control I thought of making a BUILD_VERSION_OVERRIDE that is only accepted on the command line, and if specified, it will set the BUILD_VERSION value to the overridden value. However, I don't like the idea of 2 separate variables to manage this. Using a non-cache variable doesn't allow overriding with the same variable value on the command line either. What's the best solution here for my situation? -- 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.
