#  - link-time genereated pdb files (link flag /debug + /PDB:<pdb_name>)
#
# CMake allows changing the names of each of those pdb file types by setting
# the COMPILE_PDB_NAME_<CONFIG> and PDB_NAME_<CONFIG> properties. If they are
# left empty, CMake will compute the default names itself (or rather in certain cases
# leave it up to te compiler), without actually setting the property values.
#
# For installation purposes, CMake only provides a generator expression to the
# link time pdb file path, not the compile path one, which means we have to compute the
# path to the compile path pdb files ourselves.
# See https://gitlab.kitware.com/cmake/cmake/-/issues/18393 for details.
#
# For shared libraries and executables, we install the linker provided pdb file via the
# TARGET_PDB_FILE generator expression.
#
# For static libraries there is no linker invocation, so we need to install the compile
# time pdb file. We query the ARCHIVE_OUTPUT_DIRECTORY property of the target to get the
# path to the pdb file, and reconstruct the file name. We use a generator expression
# to append a possible debug suffix, in order to allow installation of all Release and
# Debug pdb files when using Ninja Multi-Config.
