As Thiago mentioned, dynamically linking OpenSSL tends to be easier.
From what I can tell, the vcpkg directory should work with the
FindOpenssl.cmake module.
You also may have trouble if you are mixing dynamically- and statically linked
libraries!
Since they are likely linking the VC runtime in the same manner, they _cannot_
be mixed.
And, if I remember correctly, the default ‘static’ triplets in vcpkg all link
the runtime statically.
Which means Qt and all other dependencies must also be built this way
(-static-runtime for Qt).
You can also define your own triplet with dynamic lining of the VC runtime, but
I’m not familiar with the process.

Marten,
I’m now trying to do the same in Windows but having problems.
I’m using vcpkg to build openssl and the only different in the configure line
is the path to the installed vcpkgs
..\configure.bat -prefix C:\Qt\6.4.1\msvc2019_static -static -debug-and-release
-nomake examples -nomake tests -nomake benchmarks -nomake manual-tests -nomake
minimal-static-tests -openssl-linked -qtnamespace com_imaginando_qt_6_4_1 --
-DOPENSSL_ROOT_DIR="C:\vcpkg\installed\x64-windows-static\"
-DOPENSSL_USE_STATIC_LIBS=TRUE
Inside C:\vcpkg\installed\x64-windows-static\include there is the openssl folder
And inside the C:\vcpkg\installed\x64-windows-static\lib there is:
libcrypto.lib
libeay32.lib
libssl.lib
However, the result is:
CMake Error at qtbase/cmake/QtBuildInformation.cmake:490 (message):
Feature "openssl": Forcing to "ON" breaks its condition:
QT_FEATURE_openssl_runtime OR QT_FEATURE_openssl_linked Condition values dump:

qtbase/cmake/QtFeature.cmake:575 (qt_feature_module_end)
qtbase/src/CMakeLists.txt:9 (qt_feature_evaluate_features)
Trying to build without this, worked perfectly.
What am I missing here?
Thanks!

Marten,
I’ve noticed the nuance yesterday and tried but there was an error but I didn’t
read the output correctly. I had a typo in a second define,
OPENSSL_USE_STATIC_LIBS, which needed to be set to true. The following
configure line worked:
./configure -prefix /Users/nsantos/Qt/6.4.1/macos_static -static
-debug-and-release -nomake examples -nomake tests -nomake benchmarks -nomake
manual-tests -nomake minimal-static-tests -openssl-linked --
-DOPENSSL_ROOT_DIR="/Users/nsantos/Qt-Utils/openssl"
-DOPENSSL_USE_STATIC_LIBS=TRUE
Thiago, using openssl linked on Mac was a decision I have made a many years ago
and I can’t remember the reason. Maybe it is not a good decision anymore. I
know Apple has its SecureTransport framework. I might need to evaluate it again.
Thanks!

The parameters to cmake (-D*) must be passed after a separating double dash

So, this:

Should be like:

Marten,
Tried again without success. Maybe it's the directory layout. I don’t know I’m
in the dark since the the CMakeOutput.log and CMakeError.log do not even
mention ssl anywhere. Below is the new configure call:
./configure -prefix /Users/nsantos/Qt/6.4.2/macos -static -debug-and-release
-nomake examples -nomake tests -nomake benchmarks -nomake manual-tests -nomake
minimal-static-tests -openssl-linked
-DOPENSSL_ROOT_DIR="/Users/nsantos/Qt-Utils/openssl" -DOPENSSL_USE_STATIC_LIBS
Where:
> find /Users/nsantos/Qt-Utils/openssl
gives:
/Users/nsantos/Qt-Utils/openssl
/Users/nsantos/Qt-Utils/openssl/include
/Users/nsantos/Qt-Utils/openssl/include/crypto
/Users/nsantos/Qt-Utils/openssl/include/crypto/md32_common.h
…
/Users/nsantos/Qt-Utils/openssl/lib
/Users/nsantos/Qt-Utils/openssl/lib/libcrypto.a
/Users/nsantos/Qt-Utils/openssl/lib/libssl.a
Where can I find more information?
Thank you!
Best regards,
Nuno

Ah, I don’t think OPENSSL_LIBS is in use anymore!
I think it was still left printed at the end of configure, I’m not sure the
change removing it was merged into 6.4.
Please use the FindOpenSSL cmake find-module variables:
https://cmake.org/cmake/help/latest/module/FindOpenSSL.html
In your case, passing -DOPENSSL_ROOT_DIR="/Users/nsantos/Qt-Utils/openssl"
at the end of your configure line, something like this:
./configure -prefix …. -openssl-linked -- -DOPENSSL_ROOT_DIR="…"

Yes the patch required? My configure line was:

Marten,
Thanks for your reply.
I’m on branch 6.4.2 and before any configure I always call:
git submodule foreach --recursive "git clean -dfx" && git clean -dfx
Should I try with another branch?
No, it shouldn't be needed. I just configured 6.4 branch locally and it
works fine. With only
https://codereview.qt-project.org/c/qt/qtbase/+/446542
as the extra patch.
I think this might indicate that the openssl compile test fails, which
could disable the feature. But just to make sure; do you call configure
like `../qt5/configure ... -openssl-linked` ?

Nuno

Hey,
If this is a clean build I need to know which branch you are building.
If not then you could try deleting CMakeCache.txt and reconfiguring,
there were some changes around configuration of openssl recently
which may be conflicting with values in the cache.
