$ScriptPath [ ... flags/options ... ]

Flags/options:

    behaviour:

    -v
    --cmake-verbose-makefile
        configures CMake to run verbosely (by setting
        CMAKE_VERBOSE_MAKEFILE=ON)

    -d
    --debug-configuration
        use Debug configuration (by setting CMAKE_BUILD_TYPE=Debug). Default
        is to use Release

    -E
    --disable-examples
        disables building of examples (by setting BUILD_EXAMPLES=OFF)

    -T
    --disable-testing
        disables building of tests (by setting BUILD_TESTING=OFF)

    -m
    --run-make
        executes make after a successful running of CMake

    -s <dir>
    --stlsoft-root-dir <dir>
        specifies the STLSoft root-directory, which will be passed to CMake
        as the variable STLSOFT, and which will override the environment
        variable STLSOFT (if present)


    standard flags:

    --help
        displays this help and terminates
