The code is based on the code of this first tutorial, focusing on the use of cmake under Visual Studio.
Some additions/modifications have been made on the CMakeLists.txt and app.cxx files to test also some additional
cmake features described by this second tutorial, describing the basic use of cmake irrespective of the development platform.

It has been tested on both Windows (with Visual Studio) and on Linux (with Eclipse) summarized below.

Test on Windows

Download the tutorial code

[tmp]$ git clone gitolite@ciws.iasfbo.inaf.it:CIWS/Sandbox/PUB/CMakeTutorial.git

[tmp]$

Import the code into Visual Studio

Create the Build dir at the same directory level of CMakeTutorial directory, and run cmake to create a build for Visual Studio, i.e.:

With Windows Explorer browse the CMakeTutorial_Build directory and double-click on Tutorial.sln to open the project with Visual Studio.

Build and Run test

right mouse button on ALL_BUILD->Build
right mouse button on INSTALL->Build
right mouse button on RUN_TESTS->Build

To run test under Debug:

  • right mouse button on the project "app"->Properties->Configuration properties->Debugging and set:
  • Command: ./bin/app.exe
  • Command Arguments: 100
  • Environment: C:/Users/massimo/local/CMakeTutorial_Build/math/Debug (location of math.dll)
  • select the project "app"
  • Ctrl-F5

Test on Linux

Import the code into Eclipse

Create the Build dir at the same directory level of CMakeTutorial directory, and run cmake to create a build for Eclipse. 

[tmp]$ mkdir CMakeTutorial_Build
[tmp]$ cd CMakeTutorial_Build/
[CMakeTutorial_Build]$ cmake -G"Eclipse CDT4 - Unix Makefiles" -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=$HOME/local/bin ../CMakeTutorial

> * Import->"Existing Projects into Workspace" and select /home/trifoglio/tmp/CMakeTutorial_Build directory.

Build and Test under Eclipse

  • right mouse button on "Project-Debug@CMakeTutorial_Build"->Build

To Debug:

  • Run->Debug Configuration->Main->Project->Tutorial-Debug@CMakeTutorial_Build
  • Run->Debug Configuration->Main->C/C++ Application-> app/app
  • Run->Debug Configuration->Arguments-> 100
  • right mouse button on "Project-Debug@CMakeTutorial_Build" ->Debug As -> Local C/C++ Application

To Run a single test:

  • Run->Run Configuration->Main->Project->Tutorial-Debug@CMakeTutorial_Build
  • Run->Run Configuration->Main->C/C++ Application-> app/app
  • Run->Run Configuration->Arguments-> 100
  • right mouse button on "Project-Debug@CMakeTutorial_Build" ->Run As -> Local C/C++ Application

In both cases, on the Console, it generates the output:

The sum of 100 and 100 is 200
