Hello,
I discovered that CMake support into current libssh-0.8.7-1 is broken.
After you installed the development package, you just need to add this
line into a dummy CMakeLists.txt:


find_package(libssh)


and into the console you will read:


CMake Error at /usr/lib/cmake/libssh/libssh-config.cmake:21 (message):
  File or directory /usr/lib/cygssh.dll referenced by variable
  LIBSSH_LIBRARIES does not exist !


The error is correct because, if you open
/usr/lib/cmake/libssh/libssh-config.cmake, you will see this code:


if (EXISTS "${CMAKE_CURRENT_LIST_DIR}/CMakeCache.txt")
    # In tree build
    set_and_check(LIBSSH_INCLUDE_DIR "${CMAKE_CURRENT_LIST_DIR}/include")
    set_and_check(LIBSSH_LIBRARIES "${CMAKE_CURRENT_LIST_DIR}/lib/cygssh.dll")
else()
    set_and_check(LIBSSH_INCLUDE_DIR "${PACKAGE_PREFIX_DIR}/include")
    set_and_check(LIBSSH_LIBRARIES "${PACKAGE_PREFIX_DIR}/lib/cygssh.dll")
endif()


which is wrong since the right value for LIBSSH_LIBRARIES should be
"${PACKAGE_PREFIX_DIR}/bin/cygssh-4.dll" or
"${CMAKE_CURRENT_LIST_DIR}/bin/cygssh-4.dll".
After that, I downloaded the latest stable libssh-0.9.6, I tried to
build it but it crashes with an internal GCC error at compile time:


during RTL pass: final
/home/Carlo/libssh-0.9.6/src/sftp.c: In function ‘sftp_packet_read’:
/home/Carlo/libssh-0.9.6/src/sftp.c:549:1: internal compiler error: in
i386_pe_seh_unwind_emit, at config/i386/winnt.c:1275
  549 | }
      | ^


So, I downloaded the latest sources from the repository: GCC still
emits an internal compiler error, but only when building the examples.
So I configured with -DWITH_EXAMPLES=OFF and I got the base library
compiled.
Here, I verified that the macros for CMake are generated correctly
with the right names and paths.

Is it possible to fix or update this package?
Thank you very much for your time.

Sincerely.
