2.4.0: Build fails: Could not find a package configuration file provided by "boost_system"

[yurivict]

Describe the bug

configure fails:

CMake Error at /usr/local/lib/cmake/Boost-1.89.0/BoostConfig.cmake:141 (find_package):
  Could not find a package configuration file provided by "boost_system"
  (requested version 1.89.0) with any of the following names:

    boost_systemConfig.cmake
    boost_system-config.cmake

  Add the installation prefix of "boost_system" to CMAKE_PREFIX_PATH or set
  "boost_system_DIR" to a directory containing one of the above files.  If
  "boost_system" provides a separate development package or SDK, be sure it
  has been installed.
Call Stack (most recent call first):
  /usr/local/lib/cmake/Boost-1.89.0/BoostConfig.cmake:262 (boost_find_component)
  CMakeLists.txt:238 (FIND_PACKAGE)

This is because the latest versions of boost don't have boost_system.

To Reproduce
configure
