When a generated file created as the OUTPUT of an add_custom_command() command is explicitly listed as a source file for any target in the same directory scope (which usually means the same CMakeLists.txt file), CMake will automatically create a dependency to make sure the file is generated before building that target.

Nov 19, 2010 · Well, it is possible to do so with CMake's CMAKE_CONFIGURE_DEPENDS directory property. This forces CMake to reconfigure if any of the given files changed. Simple solution. The following code shows the approach for a single model file, that is used as input for the code generation:

Hi, I have a generator which is given a data file "data.txt" and then generates an include file "gen.h". "gen.h" is told to CMake to be a generated file.

Step 6: Adding a Custom Command and Generated File¶. Suppose, for the purpose of this tutorial, we decide that we never want to use the platform log and exp functions and instead would like to generate a table of precomputed values to use in the mysqrt function.

txx CMake Error at CMakeLists.txt:7 (add_library): No SOURCES given to target: works_not CMake Generate step failed. Build files cannot be ...

I want to generate the version.hpp.in file each time I run the make command. How can I do that? c++ linux file cmake · Share.

An important difference is that configure_file () creates a dependency on the source file, so CMake will be re-run if it changes. The file (COPY_FILE) sub-command does not create such a dependency. See also the file (COPY) sub-command just below which provides further file-copying capabilities.

cmake generator If you are using CMake to build your project, you can use the cmake generator to define all your requirements in CMake syntax. It creates a file named conanbuildinfo.cmake that can be imported from your CMakeLists.txt. conanfile.txt ¶ ... [generators] cmake

18.04.2017 · The file (GENERATE) command only updates the file if the contents change, just like configure_file (), so for this reason, file (GENERATE) or configure_file () are usually better alternatives if the output file is used as an input to something else. Generating Files At Build Time

Nov 29, 2014 · Outputting generated files into out-of-source build directory is an intended way to do it.

CMake is a meta build system that uses scripts called CMakeLists to generate build files for a specific environment (for example, ...

A CMake Generator is responsible for writing the input files for a native build system. Exactly one of the CMake Generators must be selected for a build …

Using a set of source files to build libraries and executables is about the most basic thing a build system needs to do.

Oct 22, 2021 · Generated Sources In CMake Builds. October 23, 2021. April 18, 2017 by Craig Scott. Using a set of source files to build libraries and executables is about the most basic thing a build system needs to do. This is relatively easy with CMake, but things get more interesting when some of the source files need to be generated as part of the build.

If we have a c++ project that uses a config.h configuration file with some custom paths or variables, we can generate it using CMake and a generic file config.h.in. The config.h.in can be part of a git repository, while the generated file config.h will never be added, as it is generated from the current environment.

Generate an output file for each build configuration supported by the current CMake Generator. Evaluate generator expressions from the input content to produce the output content. The options are: CONDITION <condition> Generate the output file for a particular configuration only if the condition is true.

18.11.2010 · With the above approach, each time the model file has changed CMake will reconfigure which results in the model being regenerated. Advanced solution The problem with the simple solution is that even for the smallest possible change in the model the entire dependencies of the generated files have to be rebuilt.
