I tried to use conan to integrate boost into my cpp Projekt. While it seems conan does install the boost libraries, CMake says

 -- Could NOT find Boost (missing: Boost_INCLUDE_DIR) (Required is at least version "1.78.0")

For the basic setup I tried to follow: https://codetrips.com/2020/03/20/1198/

And I found the question CMake not finding boost libraries from conan, but since the setup seems to be a bit different (and no solution was found), I would like to present my problem and project.

My project layout is:

    - ${project_root}/CMakeLists.txt
    - ${project_root}/conanfile.txt
    - ${project_root}/main.cpp
    - ${project_root}/build

With CMakeLists.txt:

    cmake_minimum_required(VERSION 3.16)
    project(boost_process_test)

    include(${CMAKE_BINARY_DIR}/conanbuildinfo.cmake)
    find_package(Boost 1.78.0)
    
    add_executable(test main.cpp)
    target_link_libraries(test PRIVATE Boost)

and with conanfile.txt

    [requires]
    boost/1.78.0

    [generators]
    cmake

and with main.cpp

    #include <boost/process.hpp>
    
    int main() {
        return 0;
    }

Within the build directory I called

 $ conan install ..

yielding the output:

Configuration:  [settings]  ...  build_type=Release  ...  boost/1.78.0 from 'conancenter' - Cache

When calling

 $ cmake -DCMAKE_BUILD_TYPE=Release ..

the above stated output is yielded.
