How do I fix 'Target "process_screenshot" links to: Boost::program

When I try building the SquadOVNext repository, I get this error.

Severity    Code    Description Project File    Line    Suppression State
Error       CMake Error at src/tools/process_screenshot/CMakeLists.txt:5 (target_link_libraries):
  Target "process_screenshot" links to:

    Boost::program_options

  but the target was not found.  Possible reasons include:

    * There is a typo in the target name.
    * A find_package call is missing for an IMPORTED target.
    * An ALIAS target is missing.       C:\Users\PLACEHOLDER\Documents\GitHub\SquadOVNext\src/tools/process_screenshot/CMakeLists.txt   5

All the dependencies are installed, and it compiles until this line:

target_link_libraries(process_screenshot PRIVATE
    libav
    Boost::program_options
)

CodePudding user response：

This is not how you use vcpkg. What instead you should do is set the CMAKE_TOOLCHAIN_FILE to point to vcpkg's toolchain, e.g.:

cmake -S../my/project -Bbuild -DCMAKE_TOOLCHAIN_FILE=[vcpkg-root]/scripts/buildsystems/vcpkg.cmake

Then you can use the find_package() to find boost and use predefined variables for your linking and include folders. Take a look at find_package(Boost).

EDIT: by [vcpkg-root] I mean the actual path to your vcpkg.
