グローバルにインストールされたDlibでDlibサンプルをコンパイルできない

Question

このコマンドでDlibをグローバル共有ライブラリとしてコンパイルしてインストールしましたsudo cmake --build . --target install --config Release次に、/usr/local/include/dlibに必要なファイルがあることを確認するためにダブルチェックします。

私は共有ライブラリでコンパイルするdlib/examples/CMakeLists.txtビットを変更し、ほとんどの株は以下の元であるオリジナルCMakeLists.txtの

cmake_minimum_required(VERSION 2.8.12) 
project(examples) 

# Modified lines [1] 
#include(../dlib/cmake) 
find_package(dlib REQUIRED) 
include_directories(${dlib_INCLUDE_DIRS}) 

macro(add_example name) 
    add_executable(${name} ${name}.cpp) 
    # Modified lines [2] 
    #target_link_libraries(${name} dlib::dlib) 
    target_link_libraries(${name} ${dlib_INCLUDE_LIBS}) 
endmacro() 

macro(add_gui_example name) 
    if (DLIB_NO_GUI_SUPPORT) 
     message("No GUI support, so we won't build the ${name} example.") 
    else() 
     add_example(${name}) 
    endif() 
endmacro() 

add_gui_example(face_detection_ex) 

残りが除去されます。ここで

Answer 1

私はタイプミスtarget_link_libraries(my_target ${dlib_INCLUDE_LIBS})を作ったので、それはだ、その理由を発見しました。一方、dlib_LIBRARIESまたはdlib_LIBSでなければならず、dlib_INCLUDE_LIBSではありません。

正しいCMakeLists.txtは次のとおりです。

cmake_minimum_required(VERSION 2.8.12) 
project(examples) 

# Fix error "cannot find -lopencv_dep_cudart" 
set(CUDA_USE_STATIC_CUDA_RUNTIME OFF) 

# Modified lines [1] 
# include(../dlib/cmake) 
find_package(dlib REQUIRED) 
include_directories(${dlib_INCLUDE_DIRS}) 

macro(add_example name) 
    add_executable(${name} ${name}.cpp) 
    # Modified lines [2] 
    # target_link_libraries(${name} dlib::dlib) 
    target_link_libraries(${name} ${dlib_LIBS}) 
endmacro() 

macro(add_gui_example name) 
    if (DLIB_NO_GUI_SUPPORT) 
     message("No GUI support, so we won't build the ${name} example.") 
    else() 
     add_example(${name}) 
    endif() 
endmacro() 

add_gui_example(face_detection_ex)
