其中cmake version 3.24.1, pcl version 1.12.1_3,安装方式均为brew install
官网文件为:

CMakeLists.txt内容为

cmake_minimum_required(VERSION 3.5 FATAL_ERROR)

project(pcl-matrix_transform)

find_package(PCL 1.7 REQUIRED)

include_directories(${PCL_INCLUDE_DIRS})
link_directories(${PCL_LIBRARY_DIRS})
add_definitions(${PCL_DEFINITIONS})

add_executable (matrix_transform matrix_transform.cpp)
target_link_libraries (matrix_transform ${PCL_LIBRARIES})

treminal运行指令:

mkdir build
cd build
cmake ..
运行结果及报错内容

出现报错:

CMake Error at /opt/homebrew/share/pcl-1.12/PCLConfig.cmake:63 (message):
  visualization is required but vtk was not found
Call Stack (most recent call first):
  /opt/homebrew/share/pcl-1.12/PCLConfig.cmake:357 (pcl_report_not_found)
  /opt/homebrew/share/pcl-1.12/PCLConfig.cmake:546 (find_external_library)
  CMakeLists.txt:5 (find_package)
我的解答思路和尝试过的方法

通过查找homebrew文件目录,vtk文件已通过brew install 安装

我想要达到的结果

请教一下,这种问题如何解决,使程序能够正常编译运行。
