--- Comment #6 from Sandro Mani <manisandro at gmail.com> ---
So the only other nice option I saw was to read what was passed to
target_link_libraries, do some regex magic and use that in the pc files.
However, looks like there is no way to read the target_link_libraries a
posteriori.... 

So I suppose what one could do is introduce a variable containing what is
passed to target_link_libraries and then filter that to use in the pc files.
Along the lines of i.e.:

set(POPPLER_GLIB_LIBRARIES ${GLIB2_LIBRARIES} ${CAIRO_LIBRARIES}
${FREETYPE_LIBRARIES} -lpthread)

target_link_libraries(poppler-glib poppler ${POPPLER_GLIB_LIBRARIES})

string(REGEX REPLACE <stuff> <stuff> POPPLER_GLIB_LIBRARIES_CLEANED
${POPPLER_GLIB_LIBRARIES})

# In the .pc
Libs.private=@POPPLER_GLIB_LIBRARIES_CLEANED@

Perhaps adding a comment above the target_link_libraries notifying the
developer to add varabiles to POPPLER_XXX_LIBRARIES variable instead of
directly to the target_link_libraries.

Sounds like a plan?
