ChronoConfig.cmake isn't installed in correct folder

[mablanchard]

Building Chrono 4.0.0, the CMake config. script get installed as <prefix>/<libdir>/cmake/ChronoConfig.cmake. This is somehow unfortunate because this is not a location CMake's find_package() search procedure would search for ChronoConfig.cmake, leading to errors of the kind:

-- Could NOT find Chrono (missing: Chrono_DIR)

I believe a better location would be <prefix>/<libdir>/cmake/Chrono/ChronoConfig.cmake which would allow something like the snippet below to just work:

find_package(
  Chrono CONFIG
  HINTS
    "${prefix}")

A workaround would be something like:

set(Chrono_DIR "${prefix}/lib/cmake")
find_package(
  Chrono CONFIG)
