pugixml include dir set to not found from pugixml config cmake files

I am trying to compile this project: https://github.com/computationalpathologygroup/ASAP.git from source. Pugixml is a dependency

I have built pugixml from source and set PugiXML_DIR and PUGIXML_INCLUDE_DIR And it still gives me error: "CMake Error: The following variables are used in this project, but they are set to NOTFOUND."

Things I have tried:

This is the error I get:

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
cpp/ASAP/annotation/PUGIXML_INCLUDE_DIR
   used as include directory in directory 
/cpp/ASAP/annotation
cpp/ASAP/multiresolutionimageinterface/PUGIXML_INCLUDE_DIR
   used as include directory in directory cpp/ASAP/multiresolutionimageinterface

Other information: setting PugiXML_DIR is mandatory, and the cmake looks for a file named "pugixml-config.cmake" in that directory. And the config cmake file is supposed to point to compiled lib file. But when it wasn't able to find, I simply copied the lib file I compiled to the location pugixml-config.cmake was pointing.

In ASAP versions before 4.04.2019 they play dirty games with extracting include directory from the IMPORTED target. annotation/CMakeLists.txt:30:

get_target_property(PUGIXML_INCLUDE_DIR pugixml INTERFACE_INCLUDE_DIRECTORIES)

In some cases this results in setting PUGIXML_INCLUDE_DIR variable to "-NOTFOUND", thus you got corresponded error message from CMake.

In commit 36d8bd75 they add FindPugiXML.cmake script, which handle find_package(PugiXML) call instead of configuration script shipped with PugiXML. In that find script they obtain include directory with find_path, which looks more natually:

find_path(PugiXML_INCLUDE_DIR pugixml.hpp)

Because in newer ASAP versions the configuration script (pugixml-config.cmake), shipped with PugiXML, is no longer used, one cannot hint about PugiXML location with PugiXML_DIR or PugiXML_ROOT. In case PugiXML is installed into non-system-default location, one may simply set PugiXML_INCLUDE_DIR variable to the PugiXML include directory.
