Question

我正在通过使用Visual Studio 2017的C ++爱好项目学习CMake，以及我设置它的方式，我有一个用于源代码的文件夹和一个用于测试代码的文件夹。我将源代码构建为静态库，并将测试代码构建为可执行文件（使用Catch2）。我现在的问题是这些是两个独立的目标，每当重建这些目标中的一个或两个时，我想运行测试可执行文件。现在，我可以了解如何使用ADD_CUSTOM_COMMAND运行后期构建事件，但这仅适用于单个目标。在“TARGET”之后放置多个目标会导致只使用最后一个目标（我对此进行了测试），并且复制自定义命令可能会导致测试运行两次，而且看起来代码样式也很糟糕。有没有办法优雅地做到这一点？我的CMake文件如下所示：

# CMakeList.txt : Top-level CMake project file, do global configuration
# and include sub-projects here.
#
cmake_minimum_required (VERSION 3.8)

project ("SheepyEngine")

set (CMAKE_CXX_STANDARD 17)

set (HEADER_FILES 3rdParty/CImg/CImg.h)

set (SOURCE_DIRECTORY Source)

set (TEST_DIRECTORY Test)

# Include sub-projects.
add_subdirectory ("Source")
add_subdirectory ("Test")

# Include libraries
include_directories (
    "${CMAKE_CURRENT_LIST_DIR}/3rdParty/CImg"
    "${CMAKE_CURRENT_LIST_DIR}/3rdParty/Catch2/single_include"
)


add_library (SheepyEngine STATIC 
    "${SOURCE_DIRECTORY}/Game.cpp" 
    "${SOURCE_DIRECTORY}/Game.h" 
    "${SOURCE_DIRECTORY}/GameObject.h"
    ${HEADER_FILES})

target_include_directories(SheepyEngine PRIVATE ${CMAKE_CURRENT_LIST_DIR}/3rdParty/CImg/)

add_executable(SheepyEngineTest "${TEST_DIRECTORY}/test.cpp" "3rdParty/Catch2/single_include/catch.hpp")

target_include_directories(SheepyEngineTest PRIVATE ${CMAKE_CURRENT_LIST_DIR}/3rdParty/Catch2/)

# TODO: Add tests and install targets if needed.

if(${RUN_TESTS})
    ADD_CUSTOM_COMMAND(
        TARGET SheepyEngineTest SheepyEngine
        POST_BUILD
        COMMAND ${CMAKE_CURRENT_LIST_DIR}/Build/Debug/SheepyEngineTest.exe
    )
endif()

SheepyTestProgram目标需要依赖于SheepyEngine：

target_link_libraries(SheepyEngineTest SheepyEngine)

然后add_custom_command的目标只是SheepyEngineTest（add_custom_command只接受一个目标）。

CMake在多个目标上构建后自定义命令？
