CMake가 OpenSSL 라이브러리를 찾을 수 없음

cmake를 사용하여 자체 설치하는 소프트웨어를 설치하려고합니다. commandlin cmake .. 명령을
내리면 CMakeLists.txt -------- line ---> find_package ( OpenSSL 필수) :-

 cmake ..
-- Could NOT find Git (missing:  GIT_EXECUTABLE)

다음은 오류가 발생하는 CMakeLists.txt 파일의 일부입니다.

이제 Openssl을 설치했습니다.

ssl header is here   -- > /usr/local/ssl/include/openssl/
ssl library is here  -- > /usr/local/ssl/lib/libssl.a
                          /usr/local/ssl/lib/libcrypto.a
openssl is here      -- > /usr/local/ssl/bin

내 .profile을 다음과 같이 설정했습니다.

export LD_LIBRARY_PATH=/usr/local/ssl/include/openssl:/usr/lib:/usr/local/lib:/usr/lib/pkgconfig:/usr/local/include/wx-2.8/wx:$LD_LIBRARY_PATH
export PKG_CONFIG_PATH=/usr/lib/pkgconfig
export OPENSSL_ROOT_DIR=/usr/local/ssl
export OPENSSL_LIBRARIES=/usr/local/ssl/lib/

PATH = /usr/local/ssl/bin:$PATH

이 오류를 해결하는 방법은 무엇입니까?

편집 :-
이 오류가 발생

나는 같은 문제 (openssl)가 있었고 이것은 Ubuntu 14.04.1 LTS에서 나를 위해 일했습니다. 솔루션은 Ubuntu 18.04까지 동일합니다 (테스트 됨).

sudo apt-get install libssl-dev

Ubuntu를 사용하는 경우 sudo apt install libssl-dev.

macOS에서 수정했습니다.

brew install openssl
cmake -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl -DOPENSSL_LIBRARIES=/usr/local/opt/openssl/lib

아래 링크에서 openssl을 설치하십시오 :
https://code.google.com/p/openssl-for-windows/downloads/list
그런 다음 아래 변수를 설정하십시오.

OPENSSL_ROOT_DIR=D:/softwares/visualStudio/openssl-0.9.8k_WIN32
OPENSSL_INCLUDE_DIR=D:/softwares/visualStudio/openssl-0.9.8k_WIN32/include
OPENSSL_LIBRARIES=D:/softwares/visualStudio/openssl-0.9.8k_WIN32/lib

같은 문제이며 다음 명령을 사용하여 centos 6.5에서 수정했습니다.

yum install openssl-devel

sudo apt install libssl-dev 우분투 18.04에서 작동합니다.

당신이 사용할 수있는 경우 PKG-설정을 : pkg_search_module()당신을 위해 OpenSSL을 찾을 수 있습니다.

# Search OpenSSL
find_package(PkgConfig REQUIRED)
pkg_search_module(OPENSSL REQUIRED openssl)

if( OPENSSL_FOUND )
    include_directories(${OPENSSL_INCLUDE_DIRS})
    message(STATUS "Using OpenSSL ${OPENSSL_VERSION}")
else()
    # Error; with REQUIRED, pkg_search_module() will throw an error by it's own
endif()

target_link_libraries(${YOUR_TARGET_HERE} ${OPENSSL_LIBRARIES})

cmake 모듈 (path usr / shared.cmake-3.5 / modules)에 FindOpenSSL.cmake 파일이 있습니다. # OpenSSL 검색

 find_package(OpenSSL REQUIRED) 
if( OpenSSL_FOUND )
    include_directories(${OPENSSL_INCLUDE_DIRS})
    link_directories(${OPENSSL_LIBRARIES})
    message(STATUS "Using OpenSSL ${OPENSSL_VERSION}")

target_link_libraries(project_name /path/of/libssl.so /path/of/libcrypto.so)

Fedora 27 사용자를위한 참고 사항 : 성공적으로 openssl-devel실행 하려면 패키지를 설치해야 cmake했습니다.

sudo dnf install openssl-devel

재미를 위해 OP의 질문에 대한 대체 작업 답변을 게시하십시오.

cmake -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl/ -DOPENSSL_CRYPTO_LIBRARY=/usr/local/opt/openssl/lib/

@Morwenn이 맞습니다. openssl DIR을 구성해야합니다. 그 전에 당신이 그것을 가지고 있는지 확인해야 할 수도 있습니다. 가지고 있는지 확인해야합니다. 먼저 실행 openssl version한 다음 win + r실행 openssl 하면 시스템에서 openssl로 이름이 지정되지 않을 수 있으므로 코어 디렉토리를 찾을 수 있습니다.

이것은 내가 CMakeList.txt(작동 한) 추가 한 것입니다 .

# https://cmake.org/cmake/help/latest/command/find_package.html
# in the above link, it states:
# "In Module mode, CMake searches for a file called Find<PackageName>.cmake. 
#  The file is first searched in the CMAKE_MODULE_PATH, then among the Find 
#  Modules provided by the CMake installation. If the file is found, it is
#  read and processed by CMake. It is responsible for finding the package,
#  checking the version, and producing any needed messages. Some find-modules
#  provide limited or no support for versioning; check the module documentation."
