Furthermore, it may get confused if you switch paths between runs without clearing the cache. In these days of Git everywhere, you may forget CMake and use git clean -d -f -x, that will remove all files not under source control. CMake will use whatever path the running CMake executable is in. One can start a fresh build byĭeleting the build tree or creating a separate build tree. Because CMake does not change the source tree, there is The source tree will prevent CMake from generating any files in the In-source builds, but we strongly encourage users to adopt the notion Necessary if the user performs an in-source build. (CMake does generate a "make clean" target to remove files generated Would give users the false impression that it would work as expected. CMake does not generate a "makeĭistclean" target because CMakeLists.txt files can run scripts andĪrbitrary commands CMake has no way of tracking exactly which filesĪre generated as part of running CMake. Target that cleans the build and also removes Makefiles and other Some build trees created with GNU autotools have a "make distclean" To build your project, you simply give cmake the location of the CMakeLists.txt as an argument. The "build" folder in the same directory as the root "CMakeLists.txt" is usually a good choice. So if I want to make clean, I can just rm -rf build. I usually build the project in a single folder like "build". There is no cmake clean in CMake version 2.X cmake -build C:/foo/build/ -target cleanįrom the CMake docs for 3.0.2: -clean-first = Build target 'clean' first, then build. To only view the current cache, add option -N.ĭepending on your needs, it might be useful to save your CMake configuration options in a file outside your build directory.ĬMake supports this via its presets option.įor example, adding the follwing to CMakeUserPresets.CMake 3.X offers a 'clean' target. This lists the cache of build variablesĪfter the cmake run. You can list all build variables (with help) by running cmake -LH
CMAKE LINUX COMMAND INSTALL
Note that this doesn’t affect the minimum target for third-party libraries.įor example, if you’re building for macOS 10.12 you’ll need to install Qt 5.14 or earlier and ensure that other libraries support macOS 10.12, for example by running tools/macos-setup.sh -t 10.12.ĭisable building an application bundle (Wireshark.app) on macOS CMake is used to control the software compilation process using simple platform and compiler independent configuration files, and generate native makefiles. Specify the minimum macOS version for Wireshark and each command line utility. Optional libraries have xxx_INCLUDE_DIR and xxx_LIB flags that let you Semicon Media is a unique collection of online media, focused purely on the Electronics Community across the globe. The specified path may be absolute or relative to the current working directory.
Let you set the path to a locally-compiled version of c-ares. Run CMake with one of the following command signatures to specify the source and build trees and generate a buildsystem: cmakeDCARES_INCLUDE_DIR=/your/custom/cares/include, -DCARES_LIBRARY=/your/custom/cares/lib/libcares.so
ForĮxample, you can use -DBUILD_mmdbresolve=OFF to disable mmdbresolve.
Useful variables and generators include the following:ĭon’t build the Wireshark GUI application.Įach command line utility has its own BUILD_xxx flag as well.
CMAKE LINUX COMMAND GENERATOR
Using CMake on Windows is described further in Section 2.2.12, “Generate the build files”.Īlong with specifying a generator with the -G flag you can set variables # Assumes your source directory is named "wireshark".
Run the following commands: # Starting from your Wireshark source directory, create a build directory Wireshark using Ninja in the directory wireshark-ninja you might Specifying a generator, aka a build tool. (From ComicSansMS) Some build tree s created with GNU autotools have a 'make distclean' target that cleans the build and also removes Makefiles and other parts of the generated build system.
For example: cdWireshark’s build environment can be configured using CMake on various UNIX-like platforms, including Linux, macOS, and *BSD, and on Windows.ĬMake is designed to support out-of-tree builds - so much so that in-tree builds do not work properly in all cases.Īlong with being cross-platform, CMake supports many build tools and environments including traditional make, Ninja, and MSBuild.īuilding with CMake typically includes creating a build directory and To build your project, you simply give cmake the location of the CMakeLists.txt as an argument.
