Hi Suzuki:

CMake has its own native way of generating package information
describing software (see,
<https://cmake.org/cmake/help/git-stage/manual/cmake-packages.7.html>).
So it would be worthwhile in its own right for you to generate a
native CMake package for your software to benefit those of your users
who want to use find_package in Config mode to obtain all the
information they need about your software.  In fact, it has been
argued (see
<https://cmake.org/cmake/help/git-stage/manual/cmake-packages.7.html>)
that native CMake packages are so useful that it is worthwhile
generating those for external projects that don't produce them for
themselves.

Now moving to your question, once a native CMake package describing
software has been implemented, then it should be possible, in
principle, to translate the information in that native package into
pkg-config form (for the benefit of those who prefer pkg-config to
find_package in Config mode to obtain information about a software
package).  So this is an indirect way of fulfilling your need to
generate information about your software in pkg-config form, but the
very large side benefit is you also provide that information in native
CMake package form.
