If you need several directories, separate them by the platform-specific separators ( e.g. If you have libraries in non-standard locations, it may be useful to set this variable to this directory. using the FIND_LIBRARY() command in the CMakeLists.txt files. This is used when searching for libraries e.g.
If you have headers in non-standard locations, it may be useful to set this variable to this directory. using the FIND_PATH() command in the CMakeLists.txt files. This is used when searching for include files e.g. On UNIX systems, one can use the DESTDIR mechanism in order to relocate the whole installation (see below).
#Cmake debug build install#
The content of this variable is prepended onto all install directories.
Specifies the path in which GNSS-SDR will be installed when doing make install. See the CMake documentation about this variable and the note below for more details. If CMake does not know your compiler, the contents will be empty. The default values for these flags change with different compilers. None / Debug / Release / RelWithDebInfo / MinSizeRel / Coverage / NoOptWithASM / O2WithASM / O3WithASM / ASANĪ variable which controls the type of build and some of the flags passed to the compiler. Most relevant are: Variable passed to CMake The building system honors the usual CMake This page documents the available GNSS-SDR configuration options at building $ cmake -DCMAKE_BUILD_TYPE =Debug -DENABLE_OSMOSDR =ON. Once all the required dependencies are installed in your system, the default Populates it with customizable settings for the project. When cmake isįirst run in an empty build tree, it creates a CMakeCache.txt file and The cmake executable is the CMake command-line interface. ThisĪpproach is mandatory when building GNSS-SDR, and you will get an error message That if a build directory is removed, the source files remain unaffected. To build a directory tree outside the source tree is a key feature, ensuring Systems and processor architectures, constituting a key tool for itsĬMake can handle in-place and out-of-place builds, enabling several builds from CMake is used in conjunction with nativeĬMake allows GNSS-SDR to be effortlessly built on a wide range of operating Xcode), and liberating users from choosing It can locate executables, files, and libraries to be linked against, Supports directory hierarchies and applications that depend on multiple
#Cmake debug build software#
GNSS-SDR’s building process is managed by CMake, aĬross-platform, compiler-independent, free, and open-source software tool. Binary portability and packaging options.GPU off-loading and SIMD-related options.Your last question really doesn't make sense. How do I express that the main executable will be compiled with g++ and one nested library with gcc? Don't use old style cmake unless you have to (that path is a land of nightmares)
#Cmake debug build generator#
Those functions support generator expressions. Use add_compile_definitions, add_compile_options, etc. Using CMAKE_BUILD_TYPE will result in bad builds for any multi-configuration generator!įurther more sometimes you need to set things globally and not just for one target. NOTE: How I'm using generator expressions to specify the configuration! Target_compile_definitions(foobar PRIVATE # target_compile_options, target_link_options, etc. # Add this compile definition for debug builds, this same logic works for The modern practice is to use target's and properties. How do I specify debug and release C/C++ flags using CMake? If you'd like a deeper understanding I'd suggest reading a bit about cmake in Craig Scott's book "Professional CMake: A Practical Guide This is basically the result of handling build systems that support multiple-configurations in 1 build. It's a meta-build system (IE a build system that build's build systems). If you are wondering why this is necessary it's because cmake isn't a build system.

If you are using a single configuration generator (Ninja/Unix-Makefiles) you must specify the CMAKE_BUILD_TYPE.Ĭmake -S. How do I run CMake for each target type (debug/release)?įirst off Debug/Release are called configurations in cmake (nitpick). 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. A lot of the answers here are out of date/bad.
