[sl1pkn07]

Hi, i want to get the definition "cereal_INCLUDE_DIR" from cmake with find_package(Cereal)

but only got

cereal_DIR:PATH=/usr/share/cmake/cereal

how to get the "INCLUDE_DIR" definition?

sorry for this stupid question, but this drive me crazy

greetings

This is probably better suited for stack overflow or potentially the mailing list. I'm not very well versed in cmake.

I also stumbled upon this question; It seems you are simply supposed to use add_dependencies. Say:

find_package(cereal REQUIRED)
add_dependencies(yourtarget cereal)

Also, since cereal is a header only library and typically installs itself in a sensible directory, you can probably often get away with simply including <cereal/cereal.hpp>. The find_package then only functions to communicate you need to install cereal.

Is this still the recommended way to include cereal? I'm wondering, what folder is one supposed to give to cereal_DIR? It searches for the config.cmake files which don't exist in the source directory.
