问题
I’ve tried before and had little success in the full build but even that fails now and I'm obviously missing something on windows (and yes its probably windows :P)
can someone walk me through
- finding the correct OpenSSL to compile with libssh2
- actually cmake/compiling libssh2 into libgit2 cause it keeps saying cannot find libssh2 and I'm struggling to build it again.
I'm using CMake gui For windows, trying to build a VC2015 project
The error I was getting when building libgit2 is
checking for module 'libssh2'
package 'libssh2' not found
LIBSSH2 not found. Set CMAKE_PREFIX_PATH if it is installed outside of the default search path.
even though I have put it in every possible place I can think it would look, and I have tried setting CMAKE_PREFIX_PATH ?
if anyone has successfully done it on windows I would appreciate a pointer or two as to what I'm doing wrong or should be doing
Thanks kindly Robert
回答1:
libgit2 uses the cmake pkg-config module to find libssh2. The error message is probably wrong and misleading if you don't have pkg-config installed.
I've found that the easiest way to build libgit2 with libssh2 on windows is to turn off the USE_SSH option to prevent the pkg-config search, then manually set the necessary variables. The important ones are:
LIBSSH2_FOUND (set it to TRUE)
LIBSSH2_INCLUDE_DIRS
LIBSSH2_LIBRARY_DIRS
LIBSSH2_LIBRARIES
A similar thing can also be done for openssl.

Don't feel alone... building OpenSSL is so cryptic and challenging that entire websites have sprung-up to support this.
I typically download and check-in the LIB and don't bother... the code doesn't change and it saves build time as well.
