Correct. If Find-module can not guess, you help it by setting FOO_INCLUDE_DIR and FOO_LIBRARY. > If I set XercesC_LIBRARY to the directory containing the library (not to the > fullpath of the library itself), cmake finds XercesC but sets > XercesC_LIBRARIES to the folder instead of the library, and the same for the > XercesC::XercesC target.

Find-modules are guessers and as such they do not guarantee they will find anything. Sometimes you need to help it, by setting some standard variables, https://cmake.org/cmake/help/latest/manual/cmake-developer.7.html Xxx_INCLUDE_DIR - Where to find headers for using the Xxx library. Xxx_LIBRARY - The path of the Xxx library Then, Find-module can also perform extra checks of the explicitly specified library for eg. version, symbols, functions, etc. > I use to rely on a custom FindXercesC.cmake file that was using XercesC_ROOT > to figure all this out. > Is there any way to do the same here? There seem to be no Xxx_ROOT_DIR handled by this module https://cmake.org/cmake/help/latest/module/FindXercesC.html Best regards, -- Mateusz Loskot, http://mateusz.loskot.net -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
