Fix curl find_package: locate shared version first. (#1434)
Fix curl find_package: locate shared version first. (#1434)

- Only use find_package from CMake when FORCE_BUILD_DEPS is false
- Remove stray 'CONFIG' passed to this find_package. This was left from
  the curl/cmake iteration, and breaks this initial find_package, which
  causes FindCurlEP to fallback to the second find block, preferring the
  static libcurl (causing a number of link complications later)
- Also remove 'QUIET' setting from find_package call for better feedback
  about search process.
