copied!<p>If there's never any source higher than the lx/src directory, then there's no need for the <strong>lx/CMakeLists.txt</strong> file. If there is, it should look something like this:</p> <pre><code>cmake_minimum_required(VERSION 2.8 FATAL_ERROR) project(lx) add_subdirectory(src) add_subdirectory(dir1) add_subdirectory(dir2) # And possibly other commands dealing with things # directly in the "lx" directory </code></pre> <p>...where the subdirectories are added in library dependency order. Libraries that depend on nothing else should be added first, and then libraries that depend on those, and so on.</p> <p><strong>lx/src/CMakeLists.txt</strong></p> <pre><code>cmake_minimum_required(VERSION 2.8 FATAL_ERROR) project(lx_exe) add_subdirectory(util) add_subdirectory(js) add_subdirectory(server) set(lx_source_files conf.c lx.c) add_executable(lx ${lx_source_files}) target_link_libraries(lx server) # also transitively gets the "js" and "util" dependencies </code></pre> <p><strong>lx/src/util/CMakeLists.txt</strong></p> <pre><code>set(util_source_files etc.c etc.h str.c str.h ) add_library(util ${util_source_files}) </code></pre> <p><strong>lx/src/js/CMakeLists.txt</strong></p> <pre><code>set(js_source_files interp.c interp.h js.c js.h ) add_library(js ${js_source_files}) target_link_libraries(js util) </code></pre> <p><strong>lx/src/server/CMakeLists.txt</strong></p> <pre><code>set(server_source_files request.c request.h server.c server.h ) add_library(server ${server_source_files}) target_link_libraries(server js) # also transitively gets the "util" dependency </code></pre> <p>Then, in a command prompt:</p> <pre><code>mkdir lx/bin cd lx/bin cmake .. # or "cmake ../src" if the top level # CMakeLists.txt is in lx/src make </code></pre> <p>By default, the lx executable will end up in the "lx/bin/src" directory using this exact layout. You can control what directory it ends up in by using the RUNTIME_OUTPUT_DIRECTORY target property and the set_property command.</p> <p><a href="http://www.cmake.org/cmake/help/cmake-2-8-docs.html#prop_tgt:RUNTIME_OUTPUT_DIRECTORY" rel="noreferrer">http://www.cmake.org/cmake/help/cmake-2-8-docs.html#prop_tgt:RUNTIME_OUTPUT_DIRECTORY</a></p> <p><a href="http://www.cmake.org/cmake/help/cmake-2-8-docs.html#command:set_property" rel="noreferrer">http://www.cmake.org/cmake/help/cmake-2-8-docs.html#command:set_property</a></p> <p>Refer to target_link_libraries libs either by CMake target name, if the lib is built as a CMake target via add_library, or by full path to the library file otherwise.</p> <p>See also, the output of "cmake --help-command target_link_libraries", or any other cmake command, and the full online documentation for cmake commands found here:</p> <p><a href="http://www.cmake.org/cmake/help/cmake-2-8-docs.html#section_Commands" rel="noreferrer">http://www.cmake.org/cmake/help/cmake-2-8-docs.html#section_Commands</a></p> <p><a href="http://www.cmake.org/cmake/help/cmake-2-8-docs.html#command:target_link_libraries" rel="noreferrer">http://www.cmake.org/cmake/help/cmake-2-8-docs.html#command:target_link_libraries</a></p>
