Finding correct cmake configuration for yaml-cpp library

Question

I was trying to use yaml-cpp in my project. It took me half an hour to correctly link the library by experimenting with the following names. After I finally stumbled across them

Answer 1

Most of FindXXX.cmake scripts have usage description at the top of them (as CMake comments started #). The same is true about XXXConfig.cmake (or xxx-config.cmake) scripts.

Command find_package(XXX) uses one of such scripts (the one which actually exists). So, before using this approach for discover the package, make sure that you have read the description "embedded" into such script.

In your case, yaml-cpp-config.cmake file (created in the build or in the install directory) contains following description:

# - Config file for the yaml-cpp package
# It defines the following variables
#  YAML_CPP_INCLUDE_DIR - include directory
#  YAML_CPP_LIBRARIES    - libraries to link against

so proper usage of results of find_package(yaml-cpp) is

include_directories(${YAML_CPP_INCLUDE_DIRS})
target_link_libraries(<your-target> ${YAML_CPP_LIBRARIES})
