Fixes: ``` CMake Error at bld-curl/_pkg/lib/cmake/CURL/CURLConfig.cmake:62 (add_library): add_library cannot create ALIAS target "CURL::libcurl" because target "CURL::libcurl_shared" is imported but not globally visible. Call Stack (most recent call first): CMakeLists.txt:39 (find_package) ``` Seen with cmake 3.12 when running tests/cmake with: ```shell export CMAKE_CONSUMER=/path/to/CMake-3.12.0/bin/cmake ./test.sh find_package -DBUILD_STATIC_CURL=ON ``` I don't claim to understand what this error says, why it happens in certain CMake versions, and why such workaround is necessary for what seems like rather standard export/consume configuration.
