libgdal.so failed to link CURL_OPENSSL_4

[Octavian-Zhang]

When I'm building osgEarth from source code using
mkdir build
cd build
cmake ..
cmake --build .
the following linking error was generated:

Can anybody help me solve this?

osgEarth version: 2.10.1, this can't be updated due to compatibility with legacy code.
gdal version: 3.8.4 installed with apt-get in Ubuntu 24.04
curl version: 8.11.1, compiled and installed from scratch using source code (./configure --with-openssl).

Perhaps your GDAL is built against a different version of cURL than the one you compiled by hand, and they are conflicting.
Just a guess though.
