Cmake target install#

in file, and you will want to use the syntax. If you want to capture configure time variables, you can use a. Then write a custom MyLibConfig.cmake file in your source tree somewhere. If you have no dependencies, just use MyLibConfig.cmake instead of MyLibTargets.cmake here. This file will take the targets you exported and put them in a file.

Cmake target install#

The later option is what you'll need if you have any dependencies, even just OpenMP, so I'll illustrate that method.įirst, make an install targets file (very similar to the one you made in the build directory): install( EXPORT MyLibTargets You need to make a MyLibConfig.cmake, but you can do it either by exporting your targets directly to it, or by writing it by hand, then including the targets file. That looks like this: include(CMakePackageConfigHelpers) It's usually a good idea to give CMake access to the version, so that find_package can have a version specified. It only sets the includes destination on the exported target (which is often already set by target_include_directories, so check the MyLibTargets file and make sure you don't have the include directory included twice if you want clean cmake files). The includes destination is special since a target does not install includes.

The various destinations are only needed if you have a library, static library, or program to install.

Your basic target install command looks like this: install(TARGETS MyLib Install commands cause a file or target to be 'installed' into the install tree when you make install.
