MSYS2 and libcurl, which libs to link?

I am having some big headaches linking statically libcurl in MSYS2 mingw. I installed libcurl and all the listed dependencies from here

https://packages.msys2.org/package/mingw-w64-x86_64-curl

Since I am using CodeBlocks as IDE I need to supply a whole list of libs in form of lib#?.a, please keep in mind that I know nothing of Linux world and gcc tools and command line, otherwise I wouldn't be using an IDE!

Also I am not skilled enough to compile lib packages. I just need to write some portable code to do a https post request in cpp, so I need libcurl.

Can you tell me a complete list of all the needed libs to link against ? I tried all my best but I keep getting an infinity of unresolved symbols

UPDATE

After having checked what the package config for libcurl says, I have installed all the missing libs and used the following command line:

g++.exe -o MyProg.exe obj\Release\main.o -static-libstdc++ -static-libgcc -static -m64 -lcurl -lnghttp2 -lidn2 -lssh2 -lpsl -ladvapi32 -lcrypt32 -lssl -lcrypto -lssl -lcrypto -lgdi32 -lwldap32 -lzstd -lbrotlidec -lz -lws2_32 -s

Despite that I am still getting tons of undefined references:

d:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/10.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: d:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/10.2.0/../../../../x86_64-w64-mingw32/lib/../lib\libcurl.a(gsasl.o):(.text+0x14): undefined reference to `gsasl_init'

[plus many other 'gsasl...' referrences]

d:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/10.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: d:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/10.2.0/../../../../lib\libbrotlidec.a(decode.c.o):(.text+0x2d28): undefined reference to `BrotliTransformDictionaryWord'

[plus many other 'brotli...' references]

pkg-config will tell you the necessary flags. Install it from the package mingw-w64-x86_64-pkg-config.

Run it as pkg-config --libs --static libcurl.

Copy the output into "linker flags -> other". For me the output is -L/mingw64/lib -lcurl -lnghttp2 -lidn2 -lssh2 -lpsl -ladvapi32 -lcrypt32 -lssl -lcrypto -lssl -lcrypto -lgdi32 -lwldap32 -lzstd -lbrotlidec -lz -lws2_32. Don't forget to add the --static flag, if you're not already doing so.
