Static linking of libcurl is not possible #2
Description
Currently, libcurl is not linked properly (statically), and only a reference to the DLL is created. This is an issue since the libcurl version used by EuroScope is typically used instead of any system install, and EuroScope is a major version behind. The runtime version behind behind is not an issue in general, however ought to be addressed for stability. Additionally, the correct version allows use of CURLOPT_CAINFO_BLOB, which provides one method of addressing #1.
It is not possible to link against the libcurl provided by the cURL project with the current build system, since they use different environments (MinGW-w64 vs. MSVC via xwin). At present, it seems there are two likely remedies to this issue; either:
- build libcurl from source using our own build system, which would require use of CMake or somehow getting autoconf to properly use our cross-compiling setup; or
- convert our own build system to use the w64 target instead of MSVC, and retire it and xwin.
