building pangomm

Hi,

I am not sure if this post should go here but since it is mm module....

I decided to reorganize my jhbuild framework and have to compile gtkmm.
As a dependency, I have to compile pangomm-1.4 and got an error here.
What caught my attention is the version of glibmm-2.4 == 2.62.0 and
library needed 2.64. In the meson file 

if not is_msvc
  glibmm_generate_extra_defs_dep = cpp_compiler.find_library(
    'glibmm_generate_extra_defs-2.64',
  )

  executable('generate_extra_defs', 'generate_defs_pango.cc',
    dependencies: [pangomm_build_dep, glibmm_generate_extra_defs_dep],
    install: false,
  )
endif

Why do we list library name explicitly? Is it mistake or I have to use
some special tweak here?

I am building gtkmm-3 with default jhbuild config.

Thanks.
