The Open Enclave variant of libcurl has to be built as separate project, that is, it cannot be included in CMake projects directly via add_subdirectory. See the <CMakeLists.txt> file on how to do this by using the superbuild pattern. Note that only the library/ folder should be built when using this library in other projects.

After the library is build it can be referenced via the openenclave-curl::libcurl target. See the tests/ project for details on how to do that.

Note that this build of libcurl uses mbedtls as provided by Open Enclave, it does not rely on OpenSSL. It does not make any filesystem accesses either, and so trusted CAs must be manually included in the build, as they are not fetched from the default store. Refer to the tests/ project for an example of how to do that.

To build the library and build/run tests simply build the root CMake project, e.g.

mkdir build
cd build
cmake ..
make
