cmake - osx/mac - openssl brew

Question

我正在使用以下cmake命令

# 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()

它适用于Linux和Mac - 但在Mac上它使用osx发布的libssl - 它会抛出很多弃用警告,例如 'SSL_library_init' is deprecated: first deprecated in OS X 10.7"

使用brew我已经安装了一个更新的 - openssl -offical - libssl - 我怎么能告诉pkg_search_modulecmake找到并使用brew版本？

问候

Answer 1

截至2016年底,这对我有用:

在CMakeLists.txt中:

find_package(openssl REQUIRED)

像这样运行cmake:

cmake -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl .

Answer 2

确定它工作:)

brew upgrade openssl
brew link --force openssl
pkg-config --modversion openssl
#1.0.2

删除了cmake构建文件夹并重新运行cmake ..,上面的宏现在找到1.0.2 libssl :)
