Question

我具有以下项目文件夹结构：

project
|-CMakeLists.txt
|
|-src
|  |-mybiglib
|     |-CMakeLists.txt
|
|-tests
   |-mybiglibtest
      |-CMakeLists.txt

对于单元测试项目，我具有以下CMakeLists.txt。我要测试的库是mybiglib，并且已在另一个CMakeLists.txt

中正确构建

cmake_minimum_required (VERSION 3.10.0)
include(CTest)
enable_testing()
project (mybiglibtest)

message (STATUS "Building project ${PROJECT_NAME}")

set (CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/build/${CMAKE_BUILD_TYPE}/tests)
set (Boost_USE_STATIC_LIBS ON)
set (Boost_USE_MULTITHREADED ON)
unset (Boost_INCLUDE_DIR CACHE)
unset (Boost_LIBRARY_DIRS CACHE)
set (CMAKE_PREFIX_PATH ${CMAKE_PREFIX_PATH})
find_package (Boost COMPONENTS unit_test_framework log system REQUIRED)

include_directories (${CMAKE_SOURCE_DIR}/src ${Boost_INCLUDE_DIRS} ${CMAKE_CURRENT_SOURCE_DIR})

set (TEST_SRC
  stdafx.cpp
  Test1.cpp
  )

add_executable ( ${PROJECT_NAME} ${TEST_SRC})
target_link_libraries (${PROJECT_NAME} mybiglib ${Boost_LIBRARIES})
add_custom_command (OUTPUT "${CMAKE_RUNTIME_OUTPUT_DIRECTORY}/mybiglib.dll" COMMAND ${CMAKE_COMMAND} -E copy_if_different $<TARGET_FILE:mybiglib> "${CMAKE_RUNTIME_OUTPUT_DIRECTORY}")

我在Visual Studio 2019中打开了项目。

如果我执行命令Build All，问题是.dll mybiglib.dll没有复制到tests文件夹中，因此测试无法启动。

相反，如果我执行命令Rebuild All，则将库复制到测试文件夹中，但是显然每次都进行重建很耗时。

在构建时以及不仅在重建时，我还如何复制测试文件夹中的库？

CMake无法将库复制到Visual Studio 2019中的测试文件夹
