用OpenCV找不到opencv2/opencv.hpp头文件 about xrepo-cmake HOT 8 CLOSED

-- xrepo: opencv_INCLUDE_DIR /home/XXX/.xmake/packages/o/opencv/4.5.4/e610c461a5844179809cd993282550cb/include

到这个目录，找下对应文件在哪里 ，tree 下

from xrepo-cmake.

...include/opencv4/opencv2
---aruco
---aruco.hpp
---barcode.hpp
...

from xrepo-cmake.

可以用 xrepo fetch opencv 命令看下，按理 includedirs 已经包含 opencv4 子目录了，但是你这检测到没有

你这个 cmakelists.txt 也没贴全，我也看不出什么，建议走 xrepo_target_packages 接口，而不是 cmake find_package。。

cmake 的 find_package 不一定能给你附带上 opencv4 子目录

from xrepo-cmake.

完整的CMakeLists.txt是这样的：
#指定cmake的最小版本
cmake_minimum_required(VERSION 3.4.1)

#[[
设置项目名称，它会引入两个变量 demo_BINARY_DIR 和 demo_SOURCE_DIR，
同时，cmake 自动定义了两个等价的变量 PROJECT_BINARY_DIR 和 PROJECT_SOURCE_DIR。
]]
project(demo)

#指定c++版本
#specify the C++ standard
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED True)

#Download xrepo.cmake if not exists in build directory.
if(NOT EXISTS "${CMAKE_BINARY_DIR}/xrepo.cmake")
message(STATUS "Downloading xrepo.cmake from https://github.com/xmake-io/xrepo-cmake/")
# mirror https://cdn.jsdelivr.net/gh/xmake-io/xrepo-cmake@main/xrepo.cmake

TLS_VERIFY ON)
endif()

#Include xrepo.cmake so we can use xrepo_package function.
include(${CMAKE_BINARY_DIR}/xrepo.cmake)

xrepo_package("spdlog")
xrepo_package("opencv 4.5.4")

#头文件目录，将指定目录添加到编译器的头文件搜索路径之下，指定的目录被解释成当前源码路径的相对路径。
include_directories(
${CMAKE_CURRENT_SOURCE_DIR}/src #自己写的头文件所在目录

)

#查找c++源文件
file(GLOB_RECURSE CPP_SOURCE_FILES
"${CMAKE_CURRENT_SOURCE_DIR}/src/.cpp"
"${CMAKE_CURRENT_SOURCE_DIR}/src/.h"
) #GLOB_RECURSE 查找包括子目录

add_executable(mainWorker ${CPP_SOURCE_FILES})
target_link_libraries(mainWorker spdlog opencv)

from xrepo-cmake.

CMakeLists.txt 我改成下面了：

add_executable(mainWorker ${CPP_SOURCE_FILES})
#target_link_libraries(mainWorker spdlog opencv)
xrepo_target_packages(
mainWorker
spdlog opencv
)
make的时候报的错误是：
.../.xmake/packages/o/opencv/4.5.4/e610c461a5844179809cd993282550cb/include/opencv4/opencv2/opencv.hpp:48:10: fatal error: opencv2/opencv_modules.hpp: 没有那个文件或目录
48 | #include "opencv2/opencv_modules.hpp"

from xrepo-cmake.

说明 opencv2/opencv.hpp 已经找到了，includedir 没问题，至于 opencv_modules.hpp 有没有，自己找下路径

from xrepo-cmake.

.../.xmake/packages/o/opencv/4.5.4/e610c461a5844179809cd993282550cb/include/opencv4/opencv2/ 这个目录下面opencv.hpp和opencv_modules.hpp是挨着的，opencv.hpp下面一个文件就是opencv_modules.hpp

from xrepo-cmake.

那我不知道，只要 includedirs 和路径没问题，那跟 xmake 没啥关系了
