Best cmake tutorial11/25/2023 Or if it’s even inside of the same source tree, or in some external location. Which would be very desirable, as that source file should not have to know where that header is exactly in the source tree. That the myexecutable.cxx source file tried to include the library’s header simply with “mylibrary.h”. Let’s now come back to the first compilation problem that we bumped into. # Mandatory setting for minimal CMake requirement: cmake_minimum_required ( VERSION 3.14 ) # Create a project: project ( FullExample ) # Only necessary on MacOS X to silence a warning: set ( CMAKE_MACOSX_RPATH ON ) # Build the library: add_library ( MyLibrary SHARED lib/mylibrary.h lib/mylibrary.cxx ) # Build the executable: add_executable ( MyExecutable app/myexecutable.cxx ) target_link_libraries ( MyExecutable MyLibrary ) Component Properties Very often you build a software package like: Note - CMake will be available in most package managers or even included by default Configure - Build - Install (Optional - UNIX)ĬMake follows the same general idea as practically all UNIX projects. But on UNIX-like systems building CMake is also very simple. The CMake binaries are very self-contained, so in most cases just downloading an appropriate binary is perfectly acceptable. You can always find the sources and various binaries for the latest version(s) of CMake on their main download page: /download/. If your platform’s native CMake version is older than this, you should install a newer version by hand. Keep in mind though that the ATLAS CMake code requires at least CMake version 3.2 these days. On such systems your best bet is usually just to use the native cmake executable. Practically all linux distributions provide a native package for CMake.
