Do you mean "make DESTDIR=/tmp/test" gives

/tmp/test/opt/fdo/providers.xml
/opt/fdo/Repositories/Library/DataFiles

?

MAKE_DIRECTORY is just a CMake command and knows nothing of installation
or DESTDIR.  You need to reference it yourself.  Also note the docs for
MAKE_DIRECTORY say it is deprecated and that you should use FILE:

INSTALL(CODE "
FILE(MAKE_DIRECTORY $ENV{DESTDIR}/opt/fdo/Repositories/Library/DataFiles)
")
