![]() There are several methods for debugging your CMake code.ĬMake can help you debug and profile your source code. You can set these when building if you want. CMAKE_CXX_INCLUDE_WHAT_YOU_USE for iwyu. What's the correct way to detect Release vs Debug build with modern cmake (I cant use generator expressions because i need an actual if () ) cmake build release Share Improve this question Follow asked at 11:09 bernd feinman 324 2 12 1 Do not use -config at build stage and use -D CMAKEBUILDTYPERelease at configuration stage. ![]() CMAKE_CXX_CLANG_TIDY can run clang-tidy to help you clean up your code.CMAKE_CXX_COMPILER_LAUNCHER can set up a compiler launcher, like ccache, to speed up your First, lets look at ways to debug a CMakeLists or other CMake file.There are several common utilities that CMake can integrate with to help you with your builds. Otherwise, you can set the release and debug flags separately. expands to 'Release' if Debug configuration is in use. The main feature of these expressions is that they are evaluated at build time, not at configuration time, like normal CMake variables. This feature is often used by package management software, in conjunction with the already mentioned CC, CXX, CUDACXX, and CUDAHOSTCXX environment variables. Expressions like <.> are generator exressions, introduced in CMake 2.8.You canĪdopting a convention from Linux, all build types append compiler flags from the environment variables CFLAGS, CXXFLAGS, CUDAFLAGS, and LDFLAGS ( full list). You can run CMake with CMAKEBUILDTYPEDebug for full debugging, or RelWithDebInfo for a release build with some extra debug info. I am working on a CMake project that need to set specific paths for each configuration type (e.g. Note that CMake defaults to an “empty” build type, which is neither optimized nor debug. # If there is a -lm, let's use it if (MATH_LIBRARY ) target_link_libraries (simple_lib PUBLIC $ ) endif () Optimized release build, or MinSizeRel for a minimum size release (which I’ve never used). Once you make a debug build, you can run a debugger, such as gdb or lldb on it. ![]() There are distinct flags for this mode (variables ending in DEBUG as opposed to RELEASE), as well as a generator expression value CONFIG:Debug or CONFIG:Release. RelWithDebInfo for a release build with some extra debug info. In multi-configuration generators, like many IDEs, you can pick the configuration in the IDE. You can run CMake with CMAKE_BUILD_TYPE=Debug for full debugging, or ![]() To run a C++ debugger, you need to set several flags in your build. You can print extra find call information during the cmake run to standard error by adding -debug-find (CMake 3.17+).Īlternatively, CMAKE_FIND_DEBUG_MODE can be set around sections of your CMakeLists.txt to limit debug printing to a specific region. Details: Building CMake Projects To build CMake projects. Typical values include Debug, Release, RelWithDebInfo and. More details on this will be shown in the next section.įor now, let’s watch where CMake searches for find_. Debug or Release field in the Edit build configuration combo box. Specifies the build type on single-configuration generators (e.g. trace-source=CMakeLists.txt with -trace? Find call informationĬMake scripts can search for dependent libraries, executables and more. What is the difference? How about replacing The following in JUCEHelperTargets.cmake also needs to be updated to support multiple configs.Cmake -S.
