Looks like mageia has split the c++ gmp bindings into libgmpxx-devel
make sure you have that installed.

Shouldn't that be libgmp-devel & libgmpxx-devel ?

The "Found gmp, version 6.2.0" means he found a pkg-config file.

Then after, using the data from the .pc file it tries to find gmpxx.h
and libgmpxx.so and libgmp.so.  It can find the last one, but not the
two first ( see the "missing GMPXX_LIBRARY GMP_INCLUDE_DIR" ).
