Donato,

You probably need to install pkg-config since it is required now in GDAL 2.3 
to detect openjpeg. Previous GDAL versions had a painful manual way of 
detecting openjpeg that has been simpilfied in GDAL 2.3 configure code.

If I look for openjp2 in the config.log file generated by configure, here are 
the relevant lines:

configure:27477: $PKG_CONFIG --exists --print-errors "libopenjp2 >= 2.1.0"
configure:27480: $? = 0
configure:27495: $PKG_CONFIG --exists --print-errors "libopenjp2 >= 2.1.0"
configure:27498: $? = 0
configure:27534: result: yes
configure:27544: checking for opj_setup_decoder in -lopenjp2
configure:27569: gcc -o conftest -DHAVE_AVX_AT_COMPILE_TIME -
DHAVE_SSSE3_AT_COMPILE_TIME -DHAVE_SSE_AT_COMPILE_TIME -fPIC  -g -DDEBUG -
ftrapv -fvisibility=hidden   conftest.c -lopenjp2  -lopenjp2 >&5
configure:27569: $? = 0
configure:27578: result: yes
