Install Double-conversion by running the following commands:
mkdir build &&
cd    build &&
cmake -D CMAKE_INSTALL_PREFIX=/usr        \
      -D CMAKE_POLICY_VERSION_MINIMUM=3.5 \
      -D BUILD_SHARED_LIBS=ON             \
      -D BUILD_TESTING=ON                 \
      ..                                  &&
make
        To test the results, issue: make test.
          Now, as the root user:
        
make install
          -D
          CMAKE_POLICY_VERSION_MINIMUM=3.5: This switch allows
          building this package with cmake-4.0 or newer.
        
          -D BUILD_SHARED_LIBS=ON:
          This switch forces cmake to build a shared version of the library
          instead of the static version.
        
          -D BUILD_TESTING=ON: This
          switch builds the test programs.
