   Indeed Celix currently is only build and tested on Linux and Mac. 
   I am not a windows expert, so take this with a grain of salt, but to get Celix running
under windows I think we need to do the following:
   1) Update the Celix CMake files to handle dll libraries next to so (linux) and dylib (mac)
   This is currently the error you are seeing. Apparently the cmake-generator-expresssion
TARGET_SONAME_FILE does not work with dll libraries. Btw strange, because it does work with
mac dylib libraries.
   2) Support pthread. Celix thread and mutex support is build on top of pthread. To get Celix
running on windows the easiest way would be to support pthread. If I am correct this can be
done with cygwin. 
   2) Be able do dynamically load dll libraries 
   Celix uses a load library abstraction:
   And currently there is only a dlopen implementation, but In the beginning of Celix (around
2010/2011) we also had an DLL loading abstraction. This could be reintroduced (i.e. compile
a  celix_windows_library_loader.c instead of celix_library_loader.c on windows).  
   4) If I am correct with windows C/C++ functions need to explicitly declared exported in
a library. This is currently not done and needs to be done for lib framework, utils and the
bundle activators.
   5) Setup a CI pipeline to ensure Celix works and keeps working for a windows environment.

   Hopefully this helps in getting a better overview were Celix stands with respect for Windows
