How to create a Yocto recipe for cmake with separate -dev package of header files? - cmake

Question

I am trying to write a Yocto recipe for an in-house library that uses cmake to build and install itself. Running make install from the command line, the library installs the following files (headers are somewhat abridged):
-- Installing: /prefix/lib/libreflection.so
-- Installing: /prefix/lib/libreflection.a
-- Installing: /prefix/include/reflect
-- Installing: /prefix/include/reflect/type.h
-- Installing: /prefix/include/reflect/detail
-- Installing: /prefix/include/reflect/detail/type.h
-- Installing: /prefix/include/reflect/detail/property.h
-- Installing: /prefix/include/reflect/detail/iterator
-- Installing: /prefix/include/reflect/detail/iterator/range.h
-- Installing: /prefix/include/reflect/detail/accessor.h
-- Installing: /prefix/include/reflect/property.h
-- Installing: /prefix/include/reflect/register.h
-- Installing: /prefix/include/reflect/object.h
-- Installing: /prefix/lib/cmake/libreflection/libreflection-config.cmake
-- Installing: /prefix/lib/cmake/libreflection/libreflection-config-noconfig.cmake
I would like to differentiate between a binary ".so only" Yocto package (libreflection) and a development version that additionally includes the static library, header and cmake package files (libreflection-dev).
My initial recipe is as follows, but with it both libreflection and libreflection-dev package all files:
DESCRIPTION = "C++ reflection library"
SECTION = "libs"
LICENSE = "CLOSED"
SRCREV = "${AUTOREV}"
SRCBRANCH = "master"
SRC_URI = "git://gitlab.company.com/group/${PN}.git;branch=${SRCBRANCH};protocol=ssh"
inherit cmake
S = "${WORKDIR}/git"
FILES_${PN}-dev += "${libdir}/cmake"
# The following are needed because the library is unversioned.
# See https://wiki.yoctoproject.org/wiki/TipsAndTricks/Packaging_Prebuilt_Libraries#Non-versioned_Libraries
SOLIBS = ".so"
FILES_SOLIBSDEV = ""
I have tried various changes to the FILES_${PN}* variables, but none have achieved the desired effect. Generally I either end up with packaging errors, or both libreflection and libreflection-dev include all files.
How can I adjust the recipe such that libreflection includes only the .so, and libreflection-dev includes all the files?
