21.06.2020 · I am trying to generate a config CMake file for a sample project I have. My example is made of two CMake projects: a library, which uses spdlog internally and eigen in its interface and an application, which uses the library. The idea is to learn how to create a Config.cmake file so the application can find the library. This is what I have:

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.

A simple example. This is a simple yet complete example of a proper CMakeLists. For this program, we have one library (MyLibExample) with a header file and a source file, and one application, MyExample, with one source file. # Almost all CMake files should start with this # You should always specify a range with the newest # and oldest tested ...

Building complex projects is where CMake really shines — CMake is a cross-platform Makefile generator! Simply put, CMake automatically generates the Makefiles for your project. It can do much more than that too (e.g., build MS Visual Studio solutions), but in this discussion I focus on the auto-generation of Makefiles for C/C++ projects.

Example 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.

The CMakeLists.txt file in Listing 2 consists of only three lines: The first line sets the minimum version of CMake for this project, which is major version 2, minor version 8, and patch version 9 in this example.

Example code: ------------------ # Set variable containing all source files. SET( SRCS foo1.c ) # Tell CMake that "gen.h" is a generated file

If the file is modified the build system will re-run CMake to re-configure the file and ... example PRE_BUILD COMMAND <CMAKE COMMAND HERE>) ...

Introduction ¶. 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 tree to determine what native build system is to be used. Optionally one of the Extra Generators may be selected as a variant of some of the Command-Line Build Tool Generators to produce project files for an …

(For example, it will match mylibrary.dll , MyLibrary.dll , and MYLIBRARY. ... Generate an output file for each build configuration supported by the current ...

18.04.2017 · 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.

Examples | CMake. The following example demonstrates some key ideas of CMake. Make sure that you have CMake installed prior to running this example (go here for instructions). There are three directories involved. The top level directory has two subdirectories called ./Demo and ./Hello. In the directory ./Hello, a library is built.

Oct 22, 2021 · A generator may produce a CMakeLists.txt file, for example, which means the generator has to exist at configure time before any build has been performed. If the generator is built by the project, a chicken-and-egg situation results.

CMake is a meta build tool that allows you to generate native build scripts for a range ... We by creating a CMakeLists.txt file in the root of our project.

The other three examples do always generate all the files but CMake still complains that it cannot find the generated file for the Debug ...

txt that is located with your LCM type files. A Simple Example. We'll start with a very simple example that generates a STATIC library of C language bindings:

CMake can generate project buildsystems for Unix Makefiles, Ninja, Microsoft Visual Studio, or Mac OS Xcode. Here is a basic CMakeLists.txt configuration file for building a SimpleITK C++ example program. Here is our SimpleITK C++ example file sitk_example.cxx.
