This shouldn't be a big deal -- something like this should work: ExternalProject_add(OpenSSL URL "http://www.openssl.org/source/openssl-1.0.0c.tar.gz"; URL_MD5 ff8fb85610aef328315a9decbb2712e4 CONFIGURE_COMMAND ./config --prefix="${CMAKE_CURRENT_BINARY_DIR}/OpenSSL" BUILD_IN_SOURCE 1 INSTALL_DIR "${CMAKE_CURRENT_BINARY_DIR}/OpenSSL" ) set(OPENSSL_INCLUDE_DIR "${CMAKE_CURRENT_BINARY_DIR}/OpenSSL/include") link_directories("${CMAKE_CURRENT_BINARY_DIR}/OpenSSL/libs) set(OPENSSL_LIBRARIES ssl ssleay32 ssleay32MD)
The problem is that OpenSSL doesn't handle configuration scripts in the usual way -- the configure script wants you to specify your platform/compiler string. They provide an 'automatic' script instead called config, so config --prefix=... Does mostly what you want, but they make you handle the OS X 64-bit case manually -- it wants you to run configure and tell it explicitly about the platform: ./Configure darwin64-x86_64-cc This is kind of crazy, but OK, whatever. So I need to try and figure out at configure time if it's an OS X build and if it's a 64 bit build. I can use if(APPLE) to detect an Mac platform, but there's no way I can figure out to determine if the currently selected build type is 64 bits. And I think that the stock OpenSSL distribution would completely lose its mind if you tried to configure a Universal Binary build!
