Granted I'm answering this question in 2020, so it's expected things would change. So I'm going to attempt to answer it better. Your last question really doesn't make anycodings_c sense.A lot of the answers here are out of date/bad. How do I express that the main anycodings_c executable will be compiled with g++ and anycodings_c one nested library with gcc? anycodings_c Don't use old style cmake unless you anycodings_c have to (that path is a land of anycodings_c nightmares) Those anycodings_c functions support generator expressions. Use add_compile_definitions, anycodings_c add_compile_options, etc. Using CMAKE_BUILD_TYPE anycodings_c will result in bad builds for any anycodings_c multi-configuration generator!įurther more sometimes you need to set anycodings_c things globally and not just for one anycodings_c target.

CMake anycodings_c should automatically detect and use the anycodings_c compiler appropriate for your different anycodings_c source files. Set(CMAKE_CXX_FLAGS_RELEASE_INIT "-Wall")Īs for your third question, I'm not sure anycodings_c what you are asking exactly. You can modify/add to the flags by anycodings_c specifying a toolchain file in which you anycodings_c can add anycodings_c CMAKE_FLAGS_INIT anycodings_c variables, e.g.: set(CMAKE_CXX_FLAGS_DEBUG_INIT "-Wall") There are also anycodings_c RelWithDebInfo and MinSizeRel build anycodings_c configurations. Release / Debug will add the appropriate anycodings_c flags for your compiler. Then from the root of your anycodings_c project: mkdir ReleaseĪnd for Debug (again from the root of anycodings_c your project): mkdir Debug Create anycodings_c your CMakeLists.txt in the root of your anycodings_c project. With CMake, it's generally recommended anycodings_c to do an "out of source" build.
