CMake 无法确定目标的链接器语言 - C++ [英] CMake can not determine linker language for target - C++

问题描述

我正在尝试开发一个供私人使用的引擎，我正在使用 CMake 是因为我打算将来使其成为多平台，但是开始出现一个我以前从未遇到过的错误，我尝试更改项目(IEngine) to project(IEngine CXX) 如堆栈溢出的其他问题所述，但错误仍然存​​在，这是我的 CMakeLists

I'm trying to develop an engine for private use, I'm using CMake because I intend to make it multiplatform in the future, but an error started to appear that I never came across before, I tried to change project(IEngine) to project(IEngine CXX) as said in other questions from stack overflow, but the error persists, here's my CMakeLists

cmake_minimum_required(VERSION 3.16.2)

project(IEngine)

find_package(Vulkan REQUIRED)

file(GLOB_RECURSE SRC_RENDERER
    "${IEngine_SOURCE_DIR}/src/Renderer/*.cpp"
    "${IEngine_SOURCE_DIR}/src/Renderer/*.hpp"
    "${IEngine_SOURCE_DIR}/src/Renderer/*.h")

source_group("Renderer" FILES ${SRC_RENDERER})

add_library(IEngine STATIC ${SRC_RENDERER})

if(WIN32)
    target_compile_definitions(IEngine PRIVATE VK_USE_PLATFORM_WIN32_KHR)
endif()

target_include_directories(IEngine PRIVATE Vulkan::Vulkan)
target_link_libraries(IEngine Vulkan::Vulkan)

输出:

推荐答案

我多次遇到此错误 :( 将此错误添加到您的 CMakeLists.txt 中:

I've had this error many times :( Add this to your CMakeLists.txt:

set_target_properties(IEngine PROPERTIES LINKER_LANGUAGE CXX)
