默认find_library命令最终存储结果的变量是一个缓存条目(可以理解为全局变量,且会写入CMakeCache.txt文件,在不清除CMakeCache.txt文件的情况下,每次执行cmake都会先从CMakeCache.txt载入该变量的值),而且find_library命令只要检查到有值(不为空且不为-NOTFOUND),是不会执行实际查找库的动作。因此多次对同一个变量...
find_library(var NAMES opencv_xxxx REQUIRED) # 将触发error,停止后续的执行:CMake Error at test_find_library.cmake:67 (find_library): Could not find var using the following names: opencv_xxxx 1. 2. 3. 4. 5. 6. (8).NO_DEFAULT_PATH:如果指定了此选项,则不会向搜索中添加其它路径,默认搜...
为了进行图像处理,很多开发者会选择安装PIL(Python Imaging Library)库,但PIL库已经停止更新并被其分支Pillow所取代。然而,有些开发者在尝试使用pip安装PIL时,可能会遇到以下报错信息: ERROR: Could not find a version that satisfies the requirement PIL (from versions: none)ERROR: No matching distribution found...

find_package(<package>[version][EXACT][QUIET][MODULE][REQUIRED][[COMPONENTS][components...]][OPTIONAL_COMPONENTScomponents...][NO_POLICY_SCOPE]) QUITE 参数指代,当查找出错时,屏蔽 message() 的输出。 REQUIRED 参数指代,当找不到 package 时,终止过程。
find_package(CURLREQUIRED)include_directories(${CURL_INCLUDE_DIR})target_link_libraries(curltest ${CURL_LIBRARY}) 那么cmake是如何查找的呢? find_package()命令首先会在模块路径中寻找Find.cmake,这是查找库的一个典型方式。具体查找路径依次为CMake:变量${CMAKE_MODULE_PATH}中的所有目录。如果没有,然后...
