- # Building an Installer #
- Next suppose that we want to distribute our project to other people so that they
- can use it. We want to provide both binary and source distributions on a variety
- of platforms. This is a little different from the install we did previously in
- the Installing and Testing section (Step 4), where we were installing the
- binaries that we had built from the source code. In this example we will be
- building installation packages that support binary installations and package
- management features. To accomplish this we will use CPack to create platform
- specific installers. Specifically we need to add a few lines to the bottom of
- our top-level CMakeLists.txt file.
- include(InstallRequiredSystemLibraries)
- set(CPACK_RESOURCE_FILE_LICENSE "${CMAKE_CURRENT_SOURCE_DIR}/License.txt")
- set(CPACK_PACKAGE_VERSION_MAJOR "${Tutorial_VERSION_MAJOR}")
- set(CPACK_PACKAGE_VERSION_MINOR "${Tutorial_VERSION_MINOR}")
- include(CPack)
- That is all there is to it. We start by including InstallRequiredSystemLibraries.
- This module will include any runtime libraries that are needed by the project
- for the current platform. Next we set some CPack variables to where we have
- stored the license and version information for this project. The version
- information makes use of the variables we set earlier in this tutorial. Finally
- we include the CPack module which will use these variables and some other
- properties of the system you are on to setup an installer.
- The next step is to build the project in the usual manner and then run CPack
- on it. To build a binary distribution you would run:
- cpack
- To create a source distribution you would type:
- cpack -C CPackSourceConfig.cmake
- Alternatively, run “make package” or right click the Package target and
- “Build Project” from an IDE.
- Run the installer executable found in the binary directory. Then run the
- installed executable and verify that it works.
