How to fix CMake error Could not find a package configuration file provided by "boost_unit_test_framework"

Problem:

When compiling your CMake-based C++

CMake Error at /usr/lib/x86_64-linux-gnu/cmake/Boost-1.71.0/BoostConfig.cmake:117 (find_package):
  Could not find a package configuration file provided by
  "boost_unit_test_framework" (requested version 1.71.0) with any of the
  following names:

    boost_unit_test_frameworkConfig.cmake
    boost_unit_test_framework-config.cmake

  Add the installation prefix of "boost_unit_test_framework" to
  CMAKE_PREFIX_PATH or set "boost_unit_test_framework_DIR" to a directory
  containing one of the above files.  If "boost_unit_test_framework" provides
  a separate development package or SDK, be sure it has been installed.

Solution

The error message is trying to tell you that you don’t have the boost unit test library installed (or CMake can’t find it).

On Ubuntu, for example, install it using

sudo apt -y install libboost-test-dev

On Windows you can install it using the prebuilt boost binaries for Windows.
