cmake-examples

Contents

A collection of small project examples build using CMake.

SimpleExecutable:

Just one executable to calculate a square root.

SourceOrganized:

Shared library built from the code in include/ and src/ Executable linked against this shared library

External

Executable linked against a standard external module (BZip2)

External_ROOT_FastJet

Executable linked against both ROOT and FastJet. Obviously, you need to install these packages first if you wish to try this one, or to use a standard environment from one of the CERN experiments.

How to compile?

For example, for SimpleExecutable:

cd SimpleExecutable
mkdir build
cd build
cmake ..
make -j 4
./myapp

Note that we create a build directory from which we run cmake and make. This is called an out-of-source build and is the recommended way to use cmake. If you wish to start again from scratch, just remove this directory and repeat the steps above.
