![]() LLVM_ABI_BREAKING_CHECKS:STRING Used to decide if LLVM should be built with ABI breaking checks or If you want to build LLVM as a shared library, you should use the For instance use lld withīUILD_SHARED_LIBS is only recommended for use by LLVM developers. LLVM_USE_LINKER:STRING Override the system’s default linker. Your native target with, for example, -DLLVM_TARGETS_TO_BUILD=X86. LLVM_TARGETS_TO_BUILD:STRING Control which targets are enabled. Into swap, permit only one link job per 15GB of RAM available on aģ2GB machine, specify -G Ninja -DLLVM_PARALLEL_LINK_JOBS=2. These options, when you use the Ninja generator, allow you CMAKE_JOBS:STRING Building the llvm toolchain can use a lot of resources, particularly CMAKE_INSTALL_PREFIX:PATH Path where LLVM will be installed when the “install” target is built. If you are using an IDE such as Visual Studio or Xcode, you should use To override the default from CMAKE_BUILD_TYPE. You can manually set LLVM_ENABLE_ASSERTIONS They typically slowĭown LLVM and Clang when enabled, but can be useful during development. Assertions are internal checks to help you find bugs.You can improve RAM usage by using lld, see Builds with debug information can use a lot of RAM and disk space and is.Optimizations make LLVM/Clang run faster, but can be an impediment for.This configures the optimization level for make or ninja builds. Used variables that control features of LLVM and enabled subprojects. Used LLVM-related Variables below for information about commonly Or execute cmake -help-variable VARIABLE_NAME. For full documentation, consult the CMake manual, Here are some of the CMake variables that are used often, along with aīrief explanation. You mayĪlso wish to control which targets LLVM enables, or which LLVMĬomponents are built see the Frequently Used LLVM-relatedĪfter CMake has finished running, proceed to use IDE project files, or start Tool for instructions, see the Usage section, below. ![]() To build MinGW makefiles if you have a POSIX shell reachable through the PATHĮnvironment variable, for instance. Itself is the correct one for your development environment. You intend to use is the only one reachable from the shell, and that the shell In this case, make sure that the toolset that This can fail if CMake can’t detect your toolset, or if it thinks that theĮnvironment is not sane enough. See the Options and variables section forĪ list of build parameters that you can modify. CMake will use default valuesįor all build parameters. Generate the files required for building LLVM. I mentioned above that other graphics frameworks are able to link against GLFW without installing it separately, but I am not sure how to achieve this.CMake will detect your development environment, perform a series of tests, and ![]() ![]() I suppose there is something I am just not understanding about installation and imported targets. ), the error disappears, however I do not want to install dependency projects separately from Kaycee. Here is the relevant CMakeLists file for building and installing the library: # Set Kaycee variables. I have seen other graphics libraries on GitHub that link against GLFW, like Raylib, however their install process somehow works without the need for the end user to also install GLFW. The problem I have been stuck on is how to install the library without installing all of its dependencies, in this case GLFW. The library can be built as static or shared and can be installed with cmake -install. It provides an API for drawing primitives using OpenGL onto a GLFW window, using functions like void kaycee_create_window() and void kaycee_draw_cube(). I am building a small C library called Kaycee.
