![]() ![]() While you could deduce much of that from cmake -LA, a better more direct and sure-fire way would be as per: Using CMake with GNU Make: How can I see the exact commands? to just build with with: make VERBOSE=1 I think some of people coming to this question are trying to understand how CMake is building their things exactly. gives: CMAKE_BUILD_TYPE:STRING=debugīetter way to determine the exact build options: run a verbose build! if we first set a cached value: cmake -DGREETING=bye. Note that the values are the cached values, not the defaults. Without -H we get just: CMAKE_BUILD_TYPE:STRING=debug CMAKE_INSTALL_PREFIX to decide where to install the project output.CMAKE_BUILD_TYPE to control debug vs release: Debug vs Release in CMake.We also understand that CMake feels that two of their default variables are often useful to merit the non-advanced distinction: So we see that our advanced variable GREETING2 is not present. Install path prefix, prepended onto install directories. If we remove -A we get only: // Choose the type of build, options are: None Debug Release RelWithDebInfo MinSizeRel. Plus a bunch of default defined CMake variables. Set(GREETING2 "hello2" CACHE STRING "Supersecret greeting") Set(GREETING "hello" CACHE STRING "How to greet") H was previously mentioned at: consider upvoting that answerĬMakeLists.txt cmake_minimum_required(VERSION 3.0) H: include the help strings as // My help above each setting. If you are only interested in the main configuration options of some project, you will likely want to remove the -A as it would be mostly noise. Some default CMake advanced variables include basic default compilation parameters such as: CMAKE_CXX_COMPILER:FILEPATH=/usr/bin/c++ ) variables, including those marked as advanced, do: cmake -LAHĬMake marks most but not all of its default pre-defined variables as, and you can mark you own variables as advanced with mark_as_advanced). ![]()
