chapter-08 recipe-02 Could not find a package configuration file provided by "boost_filesystem"

[Becheler]

Running the recipe leads to an error.

Expected Behavior

Running cmake should lead to no error.

Current Behavior

Somehow, the system boost version (1.71) seems to be detected, and raises an error.

Steps to Reproduce (for bugs)

$ cmake .. -DCMAKE_DISABLE_FIND_PACKAGE_Boost=ON
-- recipe-02 staged install: /home/becheler/dev/cmake-cookbook/chapter-08/recipe-02/cxx-example/build/stage
-- Boost 1.61 could not be located, Building Boost 1.61.0 instead.

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

Possible solution

Something along Boost_NO_BOOST_CMAKE ? I don't really know how to use it though, but the following works in the cxx-example/src/CMakelists.txt :

cmake_minimum_required(VERSION 3.5 FATAL_ERROR)

project(recipe-02_core LANGUAGES CXX)
set(Boost_NO_BOOST_CMAKE ON)
find_package(Boost 1.61 REQUIRED COMPONENTS filesystem)

add_executable(path-info path-info.cpp)

target_link_libraries(path-info
  PUBLIC
    Boost::filesystem
  )

Context

I am reusing this Superbuild pattern in my own projects, but they stopped working when I upgraded my ubuntu version. It is weird, because I expected the local version of boost (1.61) to always work, when apparently the system version (1.71) is detected.

Dear Arnaud, thanks a lot for reporting this and sorry for the long silence. Soon I will schedule a "sprint" on this repo to resolve some long standing issues.
