CMake find_package找不到Find <package> .cmake

Question

我制作並安裝了aruco庫，該庫將Findaruco.cmake文件放在/ usr / local / lib / cmake目錄中。 在我的CMakeLists.txt文件中

...
find_package(aruco REQUIRED)

它總是返回標准錯誤

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.

我已將環境變量$ CMAKE_PREFIX_PATH設置為以下各項，但均無效

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

唯一有效的方法是在CMakeLists中設置以下內容

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

我不確定自己在做什么錯

Answer 1

嘗試設置名為CMAKE_PREFIX_PATH CMake變量，而不是環境一。 在cmake調用期間使用-D標志：

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

但是，在AFAIR中，CMake應該將/usr/local前綴作為其默認行為。
