Installation of websocketpp

First, apply several fixes to allow building with boost-1.87 and later: 

patch -Np1 -i ../websocketpp-0.8.2-boost-1.87.patch &&
sed 's|"${WEBSOCKETPP_BOOST_LIBS}"|${WEBSOCKETPP_BOOST_LIBS}|' -i CMakeLists.txt &&
sed 's/system//' -i CMakeLists.txt

Install websocketpp by running the following commands: 

mkdir build &&
cd    build &&

cmake -D CMAKE_INSTALL_PREFIX=/usr        \
      -D CMAKE_BUILD_TYPE=Release         \
      -D CMAKE_SKIP_INSTALL_RPATH=ON      \
      -D CMAKE_POLICY_VERSION_MINIMUM=3.5 \
      -D ENABLE_CPP11=ON                  \
      -D BUILD_TESTS=OFF                  \
      -G Ninja ..

Now, as the root user: 

ninja install

Command Explanations

-D CMAKE_SKIP_INSTALL_RPATH=ON: This switch makes cmake remove hardcoded library search paths (rpath) when installing a binary executable file or a shared library. This package does not need rpath once it's installed into the standard location, and rpath may sometimes cause unwanted effects or even security issues.

-D CMAKE_POLICY_VERSION_MINIMUM=3.5: This allows building with newer CMake versions.

-D ENABLE_CPP11=ON: This builds support for the ISO C++11 standard.

-D BUILD_TESTS=OFF: This disables building tests.
