To create a CMake package, you need to first create a CMakeLists.txt file in the root directory of your project. Inside this file, you need to define the project name, version, and any required dependencies.
Next, you should create a subdirectory for your package, if necessary, and create a CMakeLists.txt file in that directory. In this file, you should define the sources, headers, and any other files required for your package.
You can then use the add_subdirectory() command in the main CMakeLists.txt file to include your package in the build process. You may also need to use the target_link_libraries() command to link your package with any required libraries.
Finally, you can use the install() command to specify where the built package should be installed on the system. This will ensure that the package is available for use by other projects and applications.
Overall, creating a CMake package involves organizing your project files, linking dependencies, and specifying installation locations to ensure that your package can be easily built and used.

What is CMake configure step?
The CMake configure step refers to the process in which CMake generates the necessary build files (e.g. Makefiles, Visual Studio project files) for compiling and building a project. During this step, CMake inspects the project's source code, dependencies, and configuration settings to create the appropriate build scripts for the target platform and build system. This step is crucial as it sets up the environment and parameters needed for the project to be successfully compiled and built.
How to set CMake build type (Debug/Release)?
To set the CMake build type to either Debug or Release, you can use the CMAKE_BUILD_TYPE variable.
Here's how you can set the build type using CMake command line:
For Debug build type:
cmake -DCMAKE_BUILD_TYPE=Debug path/to/source
For Release build type:
cmake -DCMAKE_BUILD_TYPE=Release path/to/source
Alternatively, you can also set the build type in your CMakeLists.txt file using the following syntax:
1 2 3 |
if(NOT CMAKE_BUILD_TYPE) set(CMAKE_BUILD_TYPE Debug) endif() |
This will set the default build type to Debug if no build type is specified.
Remember to regenerate your build files (e.g. makefiles, Visual Studio project files) after changing the build type using CMake.
What is the difference between CMake and Make?
CMake is a cross-platform build system generator, while Make is a build automation tool. CMake generates build files for a specific build system (such as Makefiles, Ninja, or Visual Studio project files), while Make reads and executes commands in a Makefile to build a project. CMake provides a more abstract and flexible build configuration, making it easier to work across different platforms, while Make is more concise but can be more limited in its capabilities.
