Question

我正在尝试在CMakeLists文件中指定Crypto ++库，但我总是收到错误。

这是我的CMakeLists文件：

cmake_minimum_required(VERSION 2.8)
project( Recognition )
find_package( OpenCV REQUIRED )
find_package ( CURL REQUIRED )
find_package ( CRYPTOPP REQUIRED )
add_executable( Recognition Recognition.cpp )
target_link_libraries( Recognition ${OpenCV_LIBS} ${CURL_LIBRARY} ${CRYPTOPP_LIBRARY})

以下是我得到的错误：

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

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

 CRYPTOPPConfig.cmake
 cryptopp-config.cmake

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

 -- Configuring incomplete, errors occurred!

感谢您的帮助！

CMake在包中没有Crypto ++库的模块，因此您必须提供自己的模块。您可以尝试使用following（我已经使用过一次）或谷歌搜索“查找CryptoPP cmake”。

完成文件后，将其放在某处并指向CMake以搜索该位置的文件。假设您已将其放在contrib/cmake子文件夹中的sources目录下，那么CMake代码将为：

set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/contrib/cmake")

因此，您现在需要使用find_package设置模块搜索的路径，但是请注意，您应该以命名.cmake文件的相同方式提供包名称。例如，如果您有CryptoPP.cmak e，那么您应该输入以下内容：

find_package ( CryptoPP REQUIRED )

在CMakeLists文件中指定Crypto ++库
