I got libcurl downloaded and build, I would like to add HTTPS support
but I keep getting linkage errors.
I added this flag to libcurl Externalproject_Add
-DCMAKE_USE_OPENSSL=ON
also I added link to ssl like this
set(OPENSSL_USE_STATIC_LIBS TRUE)
find_package(OpenSSL REQUIRED)
target_link_libraries(curl INTERFACE OpenSSL::SSL OpenSSL::Crypto).
I am using libcurl latest release : 7.75
My configure step find the ssl package:
Found OpenSSL: /usr/lib/x86_64-linux-gnu/libcrypto.a (found version
"1.0.2g")
I keep getting linkage errors like this:

`ossl_log_tls12_secret':

ERR_error_string_n is in libcrypto so I think your project is not
including it. Maybe it is the INTERFACE dependency specification? OTOH
we are a bit unfamiliar with cmake. Can you give us a minimal sample
cmake project that can be used to reproduce?
