Part of the problem is the term “packaging” doesn’t have a formal definition in Happy packaging! Package? Never heard of her. Or well-liked town fool to provide guidance I provide my dim, flickeringĪdvice for how to best take advantage of the CMake packaging facilities. However, with the rise of package managers likeĬonan and especially vcpkg (which makes CMake central to itsĪrchitecture), ensuring that C/C++ libraries have functional packaging routinesĪbsent an official cookbook, widespread community consensus, a qualified expert, Other sources and gently massaged into a “works for me” state.ĭue to other immense obstacles in the C/C++ package ecosystem, this has not been Inevitably, projects end up cobbling together code copied from Usage, the technical documentation extensively describes how everything works,īut gives no hints to which components of the extensive CMake ecosystem Let's talk about CMake.ĭescribing the need for a “cookbook” to walk users throughĮffective packaging of CMake projects. Set policy CMP0025 to NEW with the following code at the top of your CMakeLists.txt file before the project command: # Fix behavior of CMAKE_CXX_STANDARD when targeting macOS.Pretty sure I just failed my Calc III final. Use cmake_minimum_required to require CMake 3.0 or later, or Make sure that you do one of the following things: If you are using CMake and clang to target macOS there is a bug that can cause the CMAKE_CXX_STANDARD feature to simply not work (not add any compiler flags). CMake issue #15943 for clang users targeting macOS Then you could write use_cxx11() at the top of any CMakeLists.txt file that defines a target that uses C++11. The macro only supports GCC right now, but it should be straight-forward to expand it to other compilers. If (CMAKE_CXX_COMPILER_ID STREQUAL "GNU") If you need to support older versions of CMake (quite unlikely these days), here is a macro I came up with that you can use: macro(use_cxx11) If you know that you will always have CMake 3.1 or later available, you can just write this in your top-level CMakeLists.txt file, or put it right before any new target is defined: set (CMAKE_CXX_STANDARD 11) CMake 3.1 introduced the CMAKE_CXX_STANDARD variable that you can use. ![]()
