#   YAMLCPP_LIBRARY, where to find yaml-cpp

# There is also one IMPORTED library target,
#   yamlcpp

# By default, the dynamic libraries of yaml-cpp will be found. To find the static ones instead,
# you must set the YAMLCPP_STATIC_LIBRARY variable to TRUE before calling find_package(YamlCpp ...).

# If yaml-cpp is not installed in a standard path, you can use the YAMLCPP_DIR CMake variable
# to tell CMake where yaml-cpp is.
