Open a terminal window in the RTIMEROOT directory and create the RTIMEBUILD directory. Change to the RTIMEBUILD directory and invoke cmake using the following arguments:

    cmake -G <generator> -DCMAKE_BUILD_TYPE=<Debug | Release> \
          -DCMAKE_TOOLCHAIN_FILE=<toolchain file>  \
          -DRTIME_TARGET_NAME=<target-name>

Depending on the generator, do one of the following:

For IDE generators (such as Eclipse, Visual Studio, Xcode) open the generated solution/project files and build the project/solution.
For command-line tools (such as make, nmake, ninja) run the build-tool.

After a successful build, the output is placed in RTIMEROOT/lib/<name>

The generated build-files may contain different sub-projects that are specific to the tool. For example, in Xcode and MS Visual Studio the following targets are available:

ALL_BUILD - Builds all the projects.
rti_me_<name> - Build only the specific library. Note that that dependent libraries are built first.
ZERO_CHECK runs CMake to regenerate project-files in case something changed in the build input. This target does not need to be built manually.

For command-line tools, try <tool> help for a list of available targets to build. For example, if Unix makefiles where generated:

make help
