When I use msys2 to operate 'Using this library in your project' on window, I get the following exception, I am not familiar with cmake and don't know how to solve this problem.
I modified 'cd $MONERO_CPP/external/monero-project && make release-static -j8 && make release-static -j8' of operation 5 to 'cd $MONERO_CPP/external/monero-project && make release-static-win64 - j8 && make release-static-win64 -j8'.
Execute operation 6 to the following exception.

Does building monero-project complete successfully (with cd $MONERO_CPP/external/monero-project && make release-static-win64 - j8 && make release-static-win64 -j8)?
This would be the first step, to ensure monero-project builds successfully, and work through any build errors.
Then, monero-cpp is currently expecting to find ../external/monero-project/build/release/src/crypto/wallet/libwallet-crypto.a, which is built with monero-project on *nix systems.
On Windows, it might build this library file to a different file name (e.g. *.dll?), so we'll need to update monero-cpp to use that library file on Windows.
libwallet-crypto.a is not found, so I don't know how to make it generate this file. I see that it should depend on the following code.
The crypto/wallet/ops.h file cannot generate the required header files.
In a linux environment I see it generates the following
So the file could not be generated

I'm not very familiar with this stuff, so I'm not sure if the build is complete. I see that the build is already 100%, and the following two files are the output of my two make make1.txt make2.txt
It looks like your build is completing successfully.
Within monero-project's build directory, do you have files in release/lib, like libwallet or libwallet_merged?
Or perhaps release/src/common/libcommon?
Yes. These files have already been generated. But failed to generate 'external/monero-project/build/release/src/crypto/wallet/libwallet-crypto.a'.
Ah ok, great. This library isn't configured to work with Windows, so CMakeLists.txt makes assumptions for files that are specific to Linux/Unix, like libwallet-crypto.a. Windows will build library files with a different extension (*.dll?). It should be relatively easy to update the file paths in CMakeLists.txt and other configuration for Windows.
There's an open issue to support Windows which help is wanted for: https://github.com/monero-ecosystem/monero-cpp/issues/10.
How to modify CMakeLists.txt and window configuration? I don't get it at all, I looked at the paths inside the CMakeLists.txt and it was just the libwallet-crypto.a file missing
A new version of this library is released, v0.7.2. which updates to monero-project v0.18.0.0, which had completely removed libwallet_merged.a, resulting in the error reported in this issue. Please try the new version and let me know if you continue to have problems. Some things may still need updated for Windows. Thanks.
I have updated to the latest version, libwallet_merged.a is no longer generated, but the libwallet-crypto.a file is still missing.
I found out that libwallet-crypto.a is only built on x86_64 systems to provide asm for some wallet functions.
https://github.com/monero-ecosystem/monero-cpp/pull/18 imports that library only if it exists, and should hopefully resolve this issue.
