Couldn't find LibSSH on msys2 even the libssh-devel has installed with pacman

Question

I'm trying to compile the libnetconf2 with msys2 environment on Windows 10 OS. But I get a wired(I guess) issue about libssh.

I have installed libssh libssh2 libssh-devel libssh2-devel and the pkg-config also find the location of libssh:

$ pkg-config --modversion libssh
0.9.6

And then run the command "cmake .." in

libnetconf2/build

, which gives the error:

$ cmake ..

And then I try to compile libssh from source code, after compiling and installation, the cmake still can't find the correct libssh (Below is the log for libssh compile and install):

BTW, the LD_LIBRARY_PATH has added:

Answer 1

I have resolved this issue as the link: Libgit2 and libssh2 CMake package 'libssh2' not found

/usr/local is the prefix path that I compiled and installed the libssh from source code.

cmake -DLIBSSH_INCLUDE_DIRS=/usr/local/include/libssh -DLIBSSH_LIBRARIES=/usr/local/lib/ ..
