Description
With CMake 3.20.3, I see the following error (while still 3.16 succeeds):
```
CMake Error: install(EXPORT "pnmpi-libs" ...) includes target "pnmpi" which requires target "pnmpi_debug" that is not in any export set.
```
and the same error for `pnmpi_modules`, `pnmpi_service`, and `pnmpi_wrapper`.
I think, the reason for packaging these intermediate targets was to avoid redundant compilation of the object files. My suggestion would be to change the targets from OBJECT to STATIC, install the static libraries with EXPORT and `set(CMAKE_POSITION_INDEPENDENT_CODE ON)`.

Research direction
Reproduce the install/export failure with CMake 3.20.3, then inspect the CMake configuration for the pnmpi, pnmpi_debug, pnmpi_modules, pnmpi_service, and pnmpi_wrapper targets. The work is done when installation and export generation succeeds for these targets without the reported errors, while CMake 3.16 behavior remains intact.
