Hi,

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:

../../libcurl/libcurl_install/lib/libcurl.a(openssl.c.o): In function
`ossl_log_tls12_secret':
3703/home/travis/build/Nir-Az/librealsense/build/third-party/libcurl/lib/vtls/openssl.c:270:
undefined reference to `SSL_get_session'
3704../../libcurl/libcurl_install/lib/libcurl.a(openssl.c.o): In
function `ossl_strerror':
3705/home/travis/build/Nir-Az/librealsense/build/third-party/libcurl/lib/vtls/openssl.c:354:
undefined reference to `ERR_error_string_n'



What could be the issue?
Thanks
