CppProject is a template for a simple CMake-based C++ project. It can be used as the basis for new projects: remember to change all instances of CppProject to your new project name. An example CMake module is available to make it easy to include your project in other CMake-based projects (should be customized): FindCppProject.cmake.

Features

General directory structure common to C++ projects
Example of CMake module (cmake/Modules/FindCppProject.cmake)
Testing framework (Catch)
Install script (make install)
CPack script for packaging (make package)
Automatic API documentation (Doxygen)
Continuous Integration (Travis CI)
Code coverage analysis (Coveralls) (make coverage)
Example of how to include external dependencies (using ExternalProject module)
Separate file to specify location of project files (ProjectFiles.cmake)

Requirements

To install this project, please ensure that you have installed the following (install guides are provided on the respective websites):

Git
A C++ compiler, e.g., GCC, clang, MinGW
CMake
Doxygen (optional)
Gcov (optional)
LCOV (optional)

CppProject does not depend on any libraries. The following library is optional (see Build options):

CATCH (unit testing library necessary for BUILD_TESTS build option)

This dependency will be downloaded and configured automagically if not already present locally (requires an internet connection).

Installation

Run the following commands to download, build, and install this project. Substitute project_name with the name of your project (if you leave it out, the repository will be cloned to a local folder called cpp-project). This will customize the project targets for you. Note that project_name must not contain spaces! The --depth 1 parameter passed to git clone ensures that the git history is not downloaded. In case you would like to preserve the history of this project, omit that option.

git clone https://www.github.com/kartikkumar/cpp-project --depth 1 <project_name>
cd <project_name>
git submodule init && git submodule update
mkdir build && cd build
cmake -DPROJECT_NAME=<project_name> .. && cmake --build .

To install the header files, run the following from within the build directory:

make install

Note that dependencies are installed by fetching them online, in case they cannot be detected on your local system. If the build process fails, check the error log given. Typically, building fails due to timeout. Simply run the cmake --build . command once more.

Build options

You can pass the following, general command-line options when running CMake:

-DPROJECT_SUMMARY: set short string summary for your project
-DPROJECT_VENDOR_NAME: set short string name for vendor of your project
-DPROJECT_VENDOR_CONTACT: set short string email address for vendor of your project
-DCMAKE_INSTALL_PREFIX[=$install_dir]: set path prefix for install script (make install); if not set, defaults to usual locations
-DBUILD_SHARED_LIBS=[ON|OFF (default)]: build shared libraries instead of static
-DBUILD_MAIN[=ON|OFF (default)]: build the main-function
-DBUILD_DOXYGEN_DOCS[=ON|OFF (default)]: build the Doxygen documentation (LaTeX must be installed with amsmath package)
-DBUILD_TESTS[=ON|OFF (default)]: build tests (execute tests from build-directory using ctest -V)
-DBUILD_DEPENDENCIES[=ON|OFF (default)]: force local build of dependencies, instead of first searching system-wide using find_package()

The following command is conditional and can only be set if BUILD_TESTS = ON:

-DBUILD_COVERAGE_ANALYSIS[=ON|OFF (default)]: build code coverage using Gcov and LCOV (both must be installed; requires GCC compiler; execute coverage analysis from build-directory using make coverage)

Pass these options either directly to the cmake .. build command or run ccmake .. instead to bring up the interface that can be used to toggle options.

Project structure

This project has been set up with a specific file/folder structure in mind. The following describes some important features of this setup:

cmake/Modules : Contains CMake modules, including FindCppProject.cmake template for project-specific module
docs: Contains project-specific docs in Markdown that are also parsed by Doxygen. This sub-directory includes global_todo.md, which contains a global list of TODO items for project that appear on TODO list generated in Doxygen documentation
doxydocs: HTML output generated by building Doxygen documentation
include/CppProject: Project header files (*.hpp)
scripts: Shell scripts used in Travis CI build
src: Project source files (*.cpp), including main.cpp, which contains example main-function for project build
test: Project test source files (*.cpp), including testCppProject.cpp, which contains include for Catch
.travis.yml: Configuration file for Travis CI build, including static analysis using Coverity Scan and code coverage using Coveralls
CMakeLists.txt: main CMakelists.txt file for project (should not need to be modified for basic build)
Dependencies.cmake: list of dependencies and automated build, triggered if dependency cannot be found locally
Doxyfile.in: Doxygen configuration file, adapted for generic use within project build (should not need to be modified)
LICENSE.md: license file for project (copyright statement needs to be edited)
ProjectFiles.cmake: list of project source files to build
README.md: project readme file, parsed as main page for Doxygen documentation
