yes, I pointed USE_PAPI to the folder, which contains the papi.pc
the pc itself looks like this:
prefix=/home/s0144002/papi_ml
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include
Name: PAPI
Description: Performance API to access performance metrics on system
Version: 6.0.0.1
Libs: -L${libdir} -lpapi
Libs.private:
Cflags: -I${includedir}
the path to the pkg is: /home/s0144002/papi_ml/lib/pkgconfig
if I understood the papi.pc file correctly, the include path should be correct.
the cmake step was processed without warnings or error, but during compilation papi.h cannot be found.
