When cmake is first run in an empty build tree, it creates a CMakeCache.txt file and.

The build id is in its own source and only forces a recompile of a few files. Setting the value to false is not supported. The default value is undefined which means generate a new build each time the libraris are built. -DRTI_MANUAL_BUILDID=true - Do not automatically generate a build id.NOTE: This flags must be undefined to build shared libraries. Default is undefined which means shared libraries is built. -DRTI_NO_SHARED_LIB=true - Do not build shared libraries.The default value is not defined which means try to detect the system to build for.

This option may be useful when cmake can detect all that is needed. If an empty string is specified no system file is loaded. -DRTIME_SYSTEM_FILE= or an empty string - This file can be used to set the PLATFORM_LIBS variable used by RTI Connext DDS Micro to link with.-DRTIME_BUILD_ROOT= - Where to place the intermediate build files.-DRTIME_CMAKE_ROOT= - Where to place the CMake build files.The default value is the name of the source directory. -DRTIME_TARGET_NAME= - The name of the target (equivalant of –name to rtime-make).An example would be incorporating the RTI Connext DDS Micro source in a project tree and invoke cmake directly on the CMakeLists.txt provided by RTI Connext DDS Micro. If you compile a library with the cxx_std_11 required feature, any binary that links to it will automatically have this requirement set.The following CMake flags (-D) is understood by RTI Connext DDS Micro and may be useful when building outside of the source bundle installed by RTI. The advantage would be that it propagates the requirement to dependent targets. Since CMake 3.8 there is a new option to the target_compile_features command that allows to set the required standard for a target: target_compile_features(mylib PUBLIC cxx_std_11) Most of the options can be found in the root cmake script of OpenCV: opencv/CMakeLists.txt. It is possible to specify the standard for one individual target also: set_property(TARGET mylib PROPERTY CXX_STANDARD 11) In this reference we will use regular command line. The correct way to set the C++ standard in CMake 3.1 and later is: set(CMAKE_CXX_STANDARD 11) This causes this setting to be applied to all libraries in the. CMAKESHAREDLINKERFLAGS at the end of the file. However this will not work with the Visual studio generator, so make sure to only use this for Make/Ninja generators or use target_compile_options() to set it on a per-target scope. libraries defined in one CMakeLists.txt with the setting of.

only C or C++) using the strange generator expressions syntax: add_compile_options($:-std=c++14> $:-std=c99>) Starting with CMake 3.3 you can also make this flag only apply to a specific language (e.g. Or add_definitions(-std=c++0x) # CMake 2.8.11 or older add_compile_options(-std=c++0x) # CMake 2.8.12 or newer However, I think it is not meant to be used that way and could break in a future version. While it is only meant for add -D flags, it also works with any other compiler flag. The most straightforward solution should be using add_compile_options() if you are using version 2.8.12 or newer.įor older versions you can "abuse" add_definitions().
