CMake find_package 找不到 Find.cmake

我制作并安装了 aruco 库，它将 Findaruco.cmake 文件放在 /usr/local/lib/cmake 目录中。在我的 CMakeLists.txt 文件中

...
find_package(aruco REQUIRED)

它总是返回标准错误

By not providing "Findaruco.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "aruco", but
CMake did not find one.

Could not find a package configuration file provided by "aruco" with any of
the following names:

    arucoConfig.cmake
    aruco-config.cmake

Add the installation prefix of "aruco" to CMAKE_PREFIX_PATH or set
"aruco_DIR" to a directory containing one of the above files.  If "aruco"
provides a separate development package or SDK, be sure it has been
installed.

我已将环境变量 $CMAKE_PREFIX_PATH 设置为以下各项，但没有任何效果

/usr/local  
/usr/local/lib  
/usr/local/lib/cmake  

唯一有效的是在 CMakeLists 中设置以下内容

set(CMAKE_MODULE_PATH /usr/local/lib/cmake)

我不确定我做错了什么

尝试设置CMake变量称为CMAKE_PREFIX_PATH，不是环境一。在期间使用 -D 标志cmake调用：

cmake -D CMAKE_PREFIX_PATH=/usr/local/lib <path to source or build dir>

但是 AFAIR，CMake 应该研究一下/usr/local前缀作为其默认行为。
