Catch2没有看到我的实施文件

问题描述

我的项目树是：@H_502_1@

Name
    - Catch-tests
       -- Catch CMAKE
       -- test.cpp (included as exec in cmake)
    - include (stores headers)
       -- foo.h
    - src (stores implementation)
       -- foo.cpp
    - Cmake for entire project
    - main.cpp

因此，当我在test.cpp中包含foo.h并尝试调用在foo.h中声明并在foo.cpp中实现的函数时，Catch表示一切都失败了，没有任何实现。 CMAKE（catch2）@H_502_1@

add_executable(Catch_tests_run AbstractTests.cpp ShadingTests.cpp)

CMAKE（项目）@H_502_1@

cmake_minimum_required(VERSION 3.16)
project(Hexa)

set(CMAKE_CXX_STANDARD 20)

# GLAD is OpenGL library loader.
add_library("glad" "lib/glad/src/glad.c")
include_directories("lib/glad/include")

# SDL2 provides low level controll to keyboard,sound,video,etc.
find_package(SDL2 required)
include_directories(Hexa ${SDL2_INCLUDE_Dirs})

add_executable(Hexa main.cpp
                src/ShadingEngine.cpp
                include/ShadingEngine.h
                lib/imgui/imconfig.h

                lib/imgui/imgui_impl_sdl.cpp
                lib/imgui/imgui_impl_sdl.h)

target_link_libraries(Hexa "glad")
target_link_libraries(Hexa ${SDL2_LIBRARIES})

add_subdirectory(Catch_tests)

解决方法

我假设您在test.cpp中找不到foo.h。

如果是这种情况，您只需要一个target_include_directories（Catch_tests_run $ {CMAKE_SOURCE_DIR} / include）

这应该使foo.h可用。
